Product Overview proof air conditioning and heating and refrigeration products with automatic defrost, compressor, fan and so on through a special deal with explosion, explosion-proof type of machine. Explosion-proof products can be used in petroleum, chemical, medicine, scientific research, military warehouses and other flammable dangerous ,, mixed gas environment. Flameproof in structure, intrinsically safe, explosion-encapsulation type and other complex technology, control terminal by the safe control of the whole, does not produce any spark, safe and easy to use. Explosion-proof air conditioning without obtaining the license shall not manufacture and sale. Explosion-proof air conditioners structure and working principle of the explosion-proof air conditioning by the indoor unit and an outdoor unit connecting pipes consist of the following as the vertical air structure diagram: inlet: room air is thus sucked through the air filter dust. Outlet: the conditioned air from this blow. Drains: humidity of the room through the condenser drain generating small droplets are discharged. Connecting tube: indoor unit and outdoor unit connected by a copper pipe, whereby the flow of refrigerant. Outdoor unit: Outdoor unit consists of compressor, fan, heat exchangers, capillary (electronic expansion valve), and other electrical components. Temperature control switch: control power on and off, select the cooling and heating and adjust the temperature setting, control room temperature. Air conditioning works (heat pump) when the heat pump type air conditioner running in cooling conditions, the three-way valve switches so that all components connected. At this time, the indoor heat exchanger serves as an evaporator, and the outdoor heat exchanger functions as a condenser. From the indoor heat exchanger to the low temperature and pressure through the hot gas through the four-way valve and muffler into the gas-liquid separator. After separation of the liquid, hot gas compressed by the compressor through a high-temperature high-pressure gas sucked out Bae, gas through the four-way valve into an outdoor heat exchanger is condensed to become subcooled liquid. After supercooled liquid by capillary resistance temperature low-pressure two-phase step-down, into the interior of the evaporator heat exchanger (where indoor air is cooled), again via the four-way valve and the gas-liquid separator into the next cycle: Filters mainly used for the separation of the refrigerant and compressor oil in order to ensure efficient heat exchanger.

At this time, the indoor heat exchanger functions as a condenser, the outdoor heat exchanger functions as an evaporator. From the outdoor heat exchanger to the low temperature and pressure through the hot gas through the four-way valve and muffler into the gas-liquid separator, after separating out the liquid, heat is done compressor suction, compressed into high-pressure gaseous irresolute out through the four-way valve into the gas condensing the indoor heat exchanger (in this case, the indoor air is heated). Become too cold liquid, supercooled liquid by capillary resistance down after temperature low-pressure two-phase fluid. Access to the outdoor heat exchanger evaporator, then through the hot gas through the four-way valve and the gas-liquid separator into the next cycle. To prevent defrosting lead to decreased indoor comfort heating, the use of hot gas bypass defrost mode continuous heating. Defrosting, running and heating the same basic principle, but will defrost solenoid valve opens. From the compressor to the high temperature and pressure through the hot gas is diverted part of the entrance to the outdoor heat exchanger, the outdoor heat exchanger quickly raise the temperature to more than O ℃, melt away the frost on the outdoor heat exchanger, so that the heat exchanger is to maintain good heat transfer efficiency.
