Central air conditioning project

Refrigeration technology for air conditioning belongs to the scope of ordinary refrigeration, mainly using liquid vaporization refrigeration method. (Mainly the use of liquid vaporization process to absorb than latent heat, and the liquid pressure is different, its boiling is not the same, the lower the pressure, the lower the boiling point.) According to the different ways in which heat is transferred from a high temperature object to a low-temperature object, it can be divided into: vapor compression refrigeration and absorbent refrigeration.

Water-cooled central air conditioning contains four components, compressor, condenser, throttle device, evaporator, refrigerant in turn in the above four components cycle, compressor out of the refrigerant (refrigerant) high temperature and high pressure gas, flowing through the condenser, cooling pressure, condenser through the cooling water system to bring heat to the cooling tower discharge, refrigerant continues to flow through the throttle device , into a low-temperature low-pressure liquid that flows through the evaporator, absorbs heat and compresses it. At both ends of the evaporator is connected to the frozen water circulation system, the refrigerant in this absorption of heat will be the temperature of the frozen water reduced, so that the low temperature of the water flow to the user end, and then through the fan coil for hot exchange, the cold wind blowing out.

The transmission of new air is replaced, rather than the internal circulation principle of air-conditioning gas and the unhealthy practice of mixing old and new gases, and the fresh air outside will be automatically drawn into the room through negative pressure, and will be automatically dusted and filtered when a new air vent installed in the bedroom, room or living room window enters the room.At the same time,Then by the corresponding indoor pipe and several function room exhaust air vents，The formed circulatory system will take away the indoor exhaust gas,The formed circulatory system will take away the indoor exhaust gas,concentrated in the vents,And the exhaust exhaust gas is no longer used in circulation, the old and new wind shape good circulation.
