Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model discloses a take thermoregulation dehumidifier of steam bypass, including compressor 14, water-cooled condenser 13, air-cooled condenser 8, evaporimeter 1, vapour and liquid separator 5, cistern 6, three-way flow control valve 10, divide liquid head 2, thermal expansion valve 3, drying filter 4, check valve 9, centrifugal fan 12, solenoid valve 7 and energy adjuster 11, evaporimeter 1, air-cooled condenser 8 and centrifugal fan 12 install in an air passage. One path of the compressor 14 is connected with the air-cooled condenser 8, and the other path is connected with the water-cooled condenser 13; the air-cooled condenser 8 and the water-cooled condenser 13 are installed in parallel, and are connected with a three-way flow regulating valve 10 through a one-way valve 9, the three-way flow regulating valve 10 is connected with a liquid receiver 6, a drying filter 4 and a thermostatic expansion valve 3 sequentially through a red copper pipe, the thermostatic expansion valve 3 is connected with a liquid separation head 2, a capillary pipe of the liquid separation head 2 is connected with an evaporator 1, the evaporator 1 is connected with a gas-liquid separator 5, and the gas-liquid separator 5 is connected with a compressor 14; one end of the energy regulator 11 is connected with the exhaust end of the compressor 14, and the other end is connected with the liquid receiver 6 through the electromagnetic valve 7.
The compressor 14, the water-cooled condenser 13, the air-cooled condenser 8, the evaporator 1, the gas-liquid separator 5, the liquid receiver 6, the three-way flow regulating valve 10, the liquid separation head 2, the thermostatic expansion valve 3, the electromagnetic valve 7, the energy regulator 11, the drying filter 4 and the one-way valve 9 are connected into a sealing system through copper tubes. The high-temperature high-pressure refrigerant gas discharged from the compressor 14 enters the air-cooled condenser 8 and the water-cooled condenser 13 to be cooled, and the heat of the high-temperature high-pressure refrigerant gas is taken away by the air or cooling water in the air-cooled condenser 8 and the water-cooled condenser 13. The condensed high-pressure refrigerant liquid enters the three-way flow regulating valve 10 for confluence after passing through the one-way valve 9. The merged refrigerant sequentially passes through a liquid receiver 6 and a drying filter 4 and then enters the thermostatic expansion valve 3, and is throttled and decompressed into low-temperature and low-pressure refrigerant liquid by the thermostatic expansion valve 3. Then the refrigerant enters the evaporator 1 through the liquid separation head 2 uniformly to absorb heat in the air water for evaporation, and the evaporated low-temperature low-pressure refrigerant steam is sucked by the compressor 14 through the gas-liquid separator 5 for the next cycle.
The wet air enters the evaporator 1 to be cooled first under the forced action of the centrifugal fan 12, the temperature is reduced to be below the dew point temperature, and condensed water is separated out to reduce the moisture content of the air; then, the wet air is passed through the air-cooled condenser 8 and is subjected to constant-humidity heating, and then sent into the functional room. The flow of the refrigerant entering the air-cooled condenser 8 can be controlled by adjusting the opening of the three-way flow control valve 10, and the heating quantity of the air-cooled condenser 8 is changed, so that the air outlet temperature is adjusted. When the outlet air temperature is required to be higher, more refrigerant enters the air-cooled condenser 8, and the refrigerant entering the water-cooled condenser 13 is reduced.
The energy regulator 11 is capable of automatically controlling the flow through the energy regulator 11 based on the pressure differential between the discharge side and the suction side of the compressor 14. When the environmental temperature is lower, the electromagnetic valve 7 is opened, the unit operates at low load, the energy regulator 11 sends hot gas at the high-pressure side to the low-pressure side to replace partial load, so that the suction pressure of the compressor 14 is not lower than the lowest limit value, and the safe and reliable operation of the unit is ensured. And the energy regulator 11 is capable of automatically controlling the flow through the energy regulator according to the pressure difference between the discharge end and the suction end of the compressor. When the energy regulator 11 is opened, the flow rate of the refrigerant in the evaporator 1 is increased, but the actual evaporation load in the evaporator 1 is relatively reduced due to the neutralization of hot gas, so that the operation load of the unit is indirectly reduced, and the lower limit range of temperature regulation and dehumidification of the unit is increased.
