Structural concept of air-cooled direct expansion purified air conditioning unit

1.    The technology adopted: compared with the traditional air conditioning water system, the use of direct expansion technology, through the working order of "refrigerant-air", directly let the refrigerant in the evaporation system evaporation, such a refrigeration mode belongs to the range of direct expansion air conditioning.

2. model structure: although the appearance is various, but the basic structure is made of an outdoor unit and an indoor mechanism, to split type straight expansion air conditioning is more common.

3. internal structure: and the unit itself carries the compressor, through the power of the compressor to achieve refrigerant in the indoor and outdoor unit heat absorption circulation to handle the temperature of the air. The main components are compressor, evaporator, condenser, throttle device (expansion valve) and so on.

4. including scope: at present, the common wall-mounted air conditioning, cabinet type air conditioning, smallpox machine type air conditioning, (frequency conversion) multi-line air conditioning, roof (one-piece) type air conditioning, ceiling type duct machine, dehumidifier, precision air conditioning, etc., all belong to the scope of direct expansion air conditioning. The initial installation cost of air-cooled direct expansion air conditioner is low; the refrigeration effect is more than 20% higher than that of traditional air conditioning, and the use cost is low; flexible installation, large-scale environment is not needed, environmental refrigerant, more energy saving, and beautiful appearance.
