Quality, reliable, cost-effective, Gree air-conditioning explosion Genius! Explosion Gree air conditioner uses the most advanced heating and cooling thermostat technology environment, to build the most high-end proof air conditioners, explosion-proof air conditioning we have developed production process have passed the ISO9000 international quality system certification! Explosion-proof air conditioning also adopted a mandatory national technical supervision departments EX explosion-proof electrical certification! Ensure that the explosion of advanced and reliable air conditioning. First, natural gas, chemical industry and other sectors of some places in the enterprise, in the presence of flammable and explosive places many operating rooms, workshops, warehouses can be used in explosion-proof air conditioning need constant temperature to ensure normal production and work; in addition, explosive Staff atmospheres also want to work at a temperature suitable environment in order to improve efficiency and ensure product quality. But ordinary air-conditioning in the flammable and explosive gases dangerous places, there is the possibility of an explosion, and therefore, in such establishments must use explosion-proof air conditioning. Second, the composition of the air conditioner, air-conditioned structure consists of three parts, namely the cooling systems, air circulation system and control system. The electrical portion of the refrigeration system and air circulation systems included are: compressor, swing motor, indoor and outdoor fan motor, four-way solenoid valve, high and low voltage protection switches, etc., in addition to the general well-being of dual-temperature air-conditioning as well as auxiliary heating. Mechanical portion comprises a condenser, evaporator, capillary gas-liquid separator (liquid storage tank), dried filters and other parts. Central air conditioner control system for micro-processing chip, I O port through its acquisition / change signal signal, the power supply voltage of indoor and outdoor temperature sensor detected and the operation signal of the function keys, and these information processing, through the I / O port to drive the compressor, fan motor, four-way solenoid valve, electrical heater, and display. It can be widely used in petroleum, chemical, power, room, medical, aerospace, military and other sectors with IIB, ⅡC level, temperature class T4 explosive gas mixtures l region (or Zone 2) hazardous locations.
