It may seem intimidating to perform your own system pressure tests, but it is actually quite straightforward to do so. Below is how to measure your central air conditioning system’s pressures to help know whether or not you should contact a technician for servicing:

The equipment needed Measuring the system’s pressure requires a few tools and pieces of equipment. Below is what you need: Air conditioning manifold gauge – a basic air conditioning gauge actually consists of two related, but separate, gauges. In addition, three hoses—red, blue and yellow in color—lead to the gauge manifold that joins both gauges and their hand-valves. You will not need to use the yellow hose for measuring your system pressure. Most gauges are designed to be used with systems containing different types of refrigerants (e.g., R-22), so be sure to know which scale is appropriate for your system when referencing the gauges. Charging chart – this is a visual reference that provides detailed data about normal system pressures within both the suction and high-pressure lines. This information is available in the manufacturer’s service manual for your particular system model. • Outdoor thermometer • Adjustable wrench • The measurement procedure 1.Turn off the main power switch for the system – most central air conditioning systems have an outdoor main power switch located near the outside unit; be sure to turn off the power to the system to prevent electrical accidents or damage to the system.

2. Locate your system’s gauge connection valves – central air conditioning systems contain two refrigerant lines connected to the outside units that house the condensers and compressors. The larger diameter line is the suction line that returns gaseous refrigerants to the condenser. The smaller diameter line is the high-pressure line, which is sometimes called the liquid line. At the point where the lines enter the outside unit, look closely and you will see valves that are most likely capped shut. These valves are for the purpose of monitoring refrigerant pressures, both suction and high-pressure.…

Atomizers The principle of operation of the atomizer in something similar to the working principle of ultrasonic humidifiers. The difference between them mainly lies in the method of formation of water mist. In the atomizers water mist is formed either by blowing air under high pressure through the water through the nozzle or direct water spray from nozzles under pressure.

Due to the similarity of the principle of operation, advantages and disadvantages of atomizers and ultrasonic humidifiers are also similar. Additionally, we note quite a noticeable level of noise during operation of the atomizer.

Disk humidifiers The principle of operation of disk humidifiers are based on spraying water by using centrifugal forces of a rotating disk to a fine spray. Typically, disk humidifiers have lower maximum performance than humidifiers listed above. The advantages of disk humidifiers include low consumption of energy when compared with atomizers and ultrasonic humidifiers.

Additionally it should be noted that all types of modern humidifiers currently represent a fairly sophisticated device, equipped with modern efficient equipment and control valves. In varying degrees, moisturizers sensitive to the quality of water used and require periodic maintenance to prolong its service life.…

Steam humidifiers The most common design of humidifiers, also called steam generators. Water vapor in such devices is obtained by heating and evaporation of water, after which, as a rule, the steam force is supplied by a fan or directly in the room or in the ventilation system with the help of steam lines and injectors. The steam generators can be electric and gas. Gas humidifiers are used as an energy source for evaporation of water from natural gas. Typically, they are used where there are difficulties in allocating the necessary for the operation of the steam humidifier electrical power.

In electric steam generators steam is obtained by heating water by electricity. Electric steam humidifiers are divided into steam humidifiers with immersed electrodes and steam humidifiers with heating elements. Steam humidifiers with immersed electrodes heat the water by passing an electric current through it between submerged electrodes. For efficient operation of a humidifier of this type, the water should contain a sufficient amount of dissolved salts that provide the electrical conductivity of water. The steam generator heating elements to evaporate water using one or more electric heating elements and can work even with distilled water. The advantages of steam humidifiers air can be attributed to their relative simplicity, structural reliability, wide operating range. The main disadvantage of humidifiers this type can be considered their high energy requirements for work. Ultrasonic humidifiers. In ultrasound humidifiers water is atomized into tiny droplets by using a high-frequency oscillation and fan received water mist supplied into the space or the ventilation system. Little drops of water surface area is very large relative to the mass of water in the straw, so these drops instantly evaporate in dry air, increasing its humidity. Such humidifiers consume significantly less energy than steam humidifiers. However, their scope is somewhat narrower: ultrasonic humidifiers depend in their work on the parameters of ambient air (high relative humidity reduces the effectiveness of their work).

In addition, the evaporation of large amounts of water requires large amounts of energy. During operation of the humidifier, energy is supplied from an external source (gas or electricity), whilst ultrasonic humidifiers energy is taken from the ambient air, reducing its temperature. Under certain circumstances this can lead to undesirable effects. Furthermore, due to the more complex structures, ultrasonic humidifiers are less undemanding compared to steam humidifiers.…

Air surrounds us everywhere, and its parameters have a direct impact on many processes in animate and inanimate nature. One of the most important parameters of air is its humidity. The air, as the gas mixture can contain a certain amount of water (as water vapor).

The amount of water that can be contained in the air (per unit volume or weight of air), is not constant and depends (mostly) on the air temperature. Humidity divided into absolute (the amount of moisture in kg contained in a unit volume or weight of air at the current time) and relative (measured as a percentage and represents the absolute humidity of the air at the moment, divided by the theoretical maximum under the given parameters of air absolute humidity).Normal (comfort) for man relative humidity is 40% -70%, however, not always the air around us has such moisture. For example, in winter, the cold outdoor air contains a very small amount of moisture (at low outdoor temperature, the air’s ability to retain moisture too low). The relative humidity of outdoor air, thus, can be quite high. But, entering into the living room, the air is heated, its ability to hold moisture is increased, and the amount of moisture remains the same as in outdoor air. As a result the relative humidity is reduced to absolutely uncomfortable amounts (below 20%). Such air parameters lead to the dryness of the mucous membranes of a person, to hurt one’s eyes, scratchy throat, reduced resistance to infections, and a growing number of diseases. Low relative humidity has other negative effects. Can crack wood furniture, flooring, plants suffer, greatly increases the amount of static electricity, which is dangerous for electronics. In the production of many technical processes are also sensitive to the level of relative humidity.

Among the examples are the printing industry, warehouses, paper, wood products, tobacco products, food industry, production of electronic components and etc. etc. Thus, the ability to adjust the relative humidity is very useful, and often necessary. Humidification – the process of artificially increasing the amount of moisture contained in a unit volume or weight of air and, due to this, the increase of relative humidity. Humidification is carried out using the devices, systems, devices, called a humidifier. Basic principles and methods of humidification. Modern humidifiers are based, typically, on one of the following principles.…

Elevator Air Conditioning Elevator air conditioning has fast becoming a popular concept around the world. The primary reason for installing an elevator air conditioner is the comfort that it provides while travelling in the elevator. It stabilizes the condition of the air inside the lift car. Some elevator air conditioner can be used in countries with cold climate if a the most at is used to reverse the refrigeration cycle to warm the lift car.

One of the many benefits of installing an elevator air con is the clean air that it provides. Air is sucked from the elevator’s hoist way straight into the car using a motorised fan. The air sucked into the hoist way may be filled with dust mites, germs and bacteria. With an elevator air con, air provided is much cleaner because the cold air is the same air that comes from the car itself.…

An improvement on this very simple arrangement, as far as showers over baths are concerned, is the bath/shower mixer. This resembles an ordinary mixer tap on a bath, except that a flexible metal hose rises from the centre of the mixer to a spray head which can be fixed at varying heights on the wall above the bath.

Again the water is mixed by adjusting the hot and cold taps, and at this stage it will be coming out of the spout of the tap. When the required temperature has been reached you pull up a lever on the body of the tap and this diverts the water upwards to the spray head. Nowadays, showers in cubicles normally have what’s known as a manual mixing valve. This has two inlets, one for the hot and another for the cold supply; but the temperature is regulated by turning just one mixer knob. The flow may also be adjusted by turning another knob which is set round the outside of the temperature control. In this way you can control the water itiore quickly and positively than you could do if you had to adjust two separate taps (which tends to be a bit of a juggling act). Shower mixers are constantly being improved so that they are more convenient and safer to use. With one modern manual mixing valve, for example, the temperature of the water is controlled by turning a knurled knob, not unlike the handle of a tap. And the flow and on/off control is worked by pushing in or pulling out this knob You can therefore control the flow and temperature of the water in one movement. Another advantage of this kind of control is that the shower can be stopped instantly if the pressure on the cold side falls (as a result of a toilet being flushed or cold water being drawn off elsewhere in the house, for example). If this happened the shower would suddenly run very hot, but by flicking the control knob downwards the flow ceases. It’s not so serious if the pressure falls on the hot side, because the shower would just run cold. But again, to prevent discomfort the flow can be stopped quickly by flicking the control knob. However, prevention is better than cure and there are ways of organising the plumbing so that this problem can’t arise. To alleviate the danger it’s best to run the 15mm (1/2in) cold water supply pipe to the shower direct from the cold water storage cistern and not as a branch from the 22mm (¾in) distribution pipe to the bathroom. This will supply a continuous volume of cold water provided the cistern is working properly. Thermostatic valves Of course it may mean too much of an upheaval to lay in a new pipe run, but instead you could install a special thermostatic mixing valve. This enables you to pre-set the temperature of the shower water and this will remain constant despite fluctuations of pressure in …

The sub-main underneath the road is tapped by the ‘communication pipe’ which ends at the authority’s stop-valve. This is usually situated under the pavement about 300mm (1ft) outside the boundary of your property.

The stop-valve is located at the bottom of a vertical guard’ pipe — about 1 meter (39in) deep — which is covered at the surface by a hinged metal cover. It should only be operated by the water authority and requires a special key to turn it. But in a real emergency you may be able to turn it yourself. In old houses it may be the only way of turning off the water supply. After this stop-valve the water enters the service pipe and from then on all pipes become your responsibility. The service pipe continues under the wall of the property at a depth of at least 750mm (2ft Gin) to protect it from frost —though some water authorities insist that it should be 900mm (3f1) deep. As it travels under the house wall or foundation it usually goes through an earthenware pipe to protect it from possible settlement which might cause it to fracture. To prevent any risk of freezing in cold weather the service pipe should not emerge above ground level until it is at least 600mm (2ft) inside the inside wall surface.

Up to about 40 years ago, service pipes were usually made of lead (in tact the word plumbing originally stemmed from the Latin word for lead — plumbum). Today copper and polythene are used instead. The latter is particularly good as it is a poor conductor of heat and is less prone to freezing and fracture.…

The service pipe continues under the wall near the kitchen sink, which means that it is often attached to the inner face of the outside wall. This is contrary to the recommendation that it should be attached to an inside wall, and so such a pipe should be lagged with insulation material.

The pipe should also be insulated if it comes through any sub-ground floor cavity where it would be subjected to the icy blasts of winter from under-floor ventilation. Again these precautions are both intended to minimize the risk of frost damage. When the service pipe rises above the ground floor it is called the ‘rising main’ and it eventually terminates in the supply cistern, which is usually in the roof cavity. The householder’s main stop-valve is usually found on the rising main a little way above floor level. This is the most important tap’ in the house. In any plumbing emergency — when bursts or leaks occur, for example, your first action should be to turn this tap off, thus isolating the house system from the mains water supply. The stop-valve should always be turned off when you go away if the house is going to be empty. In old houses the location of the stop- valve may vary considerably, it may be in the cellar, under the stairs, or even under a cover beneath the front path — or it may not exist at all, in which case the authority’s stop-valve is the only control. Branch supply pipes At least one ‘branch’ supply pipe eaves the rising main close above the stop-valve and drain tap — this is to the tap over the kitchen sink. This tap must be supplied direct from the main supply as it is supposed to provide all drinking and cooking water. Water which has been in a storage cistern is no longer considered drinkable, sometimes termed ‘potable’, as it may be slightly contaminated by debris in the storage cistern. Other branches may be taken at this point to an outside tap. or to a washing machine or dishwasher. The rising main continues upwards and while its ultimate destination is the cold water storage cistern the pipework in between will vary from house to house, depending on whether a ‘direct’ or ‘indirect’ system has been installed. In many areas indirect systems must be installed in new buildings, yet in Western Europe direct systems are the rule. Indirect systems have been encouraged because of the difficulty in maintaining constant mains pressure particularly at times of peak demand.

Routing of most supplies through the storage cistern evens out fluctuations, and it also rules out the risk of ‘back siphonage whereby dirty water could be sucked back into the mains supply — though this rarely occurs. The 1976 drought in the UK provided good reason for indirect systems, since each house had an emergency supply in the storage cistern if the mains water had to be shut off.…
