Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in fig. 1, an explosion-proof air conditioner for ammunition storehouses comprises a compression condensing unit, an evaporation air supply unit, a decompression protection unit and a high-low pressure control unit; the compression and condensation unit comprises a compressor 1 and a condenser 6; the air outlet of the compressor 1 is connected with the inlet of the condenser 6 through a four-way reversing valve 4; the outlet of the condenser 6 is connected with the inlet of the evaporator 9; the evaporation air supply unit comprises an evaporator 9 and a centrifugal fan 10; the outlet of the evaporator 9 is connected with the compressor 1; the centrifugal fan 10 is arranged on one side of the evaporator 9; the pressure reduction protection unit comprises a main capillary 15 and a bypass capillary 14; the main capillary 15 is respectively connected with the outlet of the condenser 6 and the inlet of the evaporator 9; the bypass capillary 14 is connected with the main capillary 15 in parallel; the inlet of the branch of the bypass capillary tube 14 is provided with a pressure valve; the high-low pressure control unit comprises a low pressure meter, a low pressure controller 2, a high pressure meter and a high pressure controller 3; the low pressure meter and the low pressure controller 2 are connected in parallel on a first conduit, and the first conduit is connected with a compressor air inlet pipe; the high-pressure gauge and the high-pressure controller 3 are connected on a second guide pipe in parallel, and the second guide pipe is connected with the air outlet pipe of the compressor.
The working condition is as follows:
the gas compressed by the compressor flows to the condenser, and flows to the decompression protection unit after being condensed, and when the compressor operates at normal temperature, the refrigerant is mainly throttled by the main capillary tube; when the pressure reaches a set value of the first pressure valve when the compressor operates in a high-temperature environment, the first pressure valve is opened, and the first bypass capillary tube enables refrigerant to pass through; when the pressure reaches a second pressure valve set point, the second pressure valve opens and the second bypass capillary tube allows refrigerant to pass through. The total flow of the bypass capillary tube and the main capillary tube in parallel corresponds to the flow required by the air conditioner when the air conditioner operates under the T3 working condition. After passing through the decompression protection unit, the gas flows to the evaporator and then flows back to the compressor through the evaporator. The low pressure meter, the low pressure controller, the high pressure meter and the high pressure controller are respectively connected to the guide pipes at the air inlet end and the air outlet end of the compressor, the air inlet pressure and the air outlet pressure of the compressor are detected, and when the air inlet pressure and the air outlet pressure are too low or too high, the power supply is cut off to protect the compressor.
