Abstract

With the improvement of people's living standard。 The growing number of people use air conditioners is more and more。 Then, people pay more attention on all aspects of the functions of the air conditioners。

As the equipment to regulate the temperature by heat transfer, the air conditioning work follows the basic thermodynamic processes, such as the refrigeration cycle in thermodynamics, the cooling capacity and so on。 By calculating the circulation in the process of heat transfer, heat transfer coefficient can be satisfied certain cooling capacity requirements of air conditioning for each part of the general parameters, and with the cooperation of a reasonable size, and can get the optimal performance。

As the four major parts of the air conditioning equipment, the two is the condenser and evaporator, which is an important part of the air conditioner。 Evaporator and condenser refrigeration capacity, work efficiency, etc。 directly affect the performance of air conditioning。 Condenser, evaporator and other design is reasonable or not, directly affect the energy consumption of air-conditioning, supplies further affect the cost of air conditioning, market share and so on。 Calculation of air supply and air supply parameters according to the cooling load。 On the basis of, according to the specific conditions and design requirements determined the economic and reasonable air processing scheme, selection of reliable and efficient air handling equipment, selection of vibration and noise of outstanding brand compressor, vibration, noise excellent fan motor selection selection of high performance outdoor fan (low noise, large air volume)

In addition, the subject also through research, the current domestic market share of major air conditioning brands, the public attention, and the direction of new technology research and development, and so on。 At last, the paper briefly introduces the design criteria of the compressor, capillary tube and so on in the four pieces of air conditioner。 It also introduces some important auxiliary equipment in the air conditioning system。
