Because of this, it's mainly found in large buildings for example apartment complexes and office buildings. The key reason why this type of air-conditioning can be used instead of window units or portable air conditioners is because they're cheaper to run in the long run. Window units are usually only great for small rooms and therefore are improper for cooling large areas.

Central air units really are a number of machines and parts that work together to cool down the air. Generally another space like a small room is going to be needed to install this method. This kind of air conditioners includes four different parts or systems. They are the compressor, which will be larger than ordinary ac compressors, condenser, evaporator and the thermostatic expansion valve. If these parts problem because they're also present in refrigerators, the real difference being that they may be bigger. You will discover basically two different types of central heat and air units. The direct expansion system also known as the DX system and the chilled water system will be the 2 basic types.

The DX system will use a large compressor and condenser which will be set up in one room and the cooling coil and evaporator will be set up in another room. The chilled air is going to be distributed via air ducts to various rooms. This technique can be used in smaller buildings and it is the greater common of these two types. The chilled water method is housed in a single room and uses a sophisticated system using brine treatment for cool the environment. The machine is a lot more noisy and complex to operate meaning it takes qualified technicians to keep it running efficiently. Chilled water systems can be used as large buildings. The largest advantage a chilled system has is when there's leak inside the pipe only water is lost and not expensive refrigerant.

As far as DX central air conditioning units go, there are a number of players on the market today for instance, Whirlpool, Samsung, LG, GE and so on. Every one has their websites that makes it easy to find prices and size. As far Chilled water systems go, you will find only a few manufacturers which make them. The reason for this is because they're more complicated and expensive for make. A few of the firms that get this to type of system are GE and Westinghouse. Aircon servicing singapore
