This evaporimeter 12 is parts very important in the large part of refrigeration four, and the refrigerant liquid of low-temp low-pressure, by evaporimeter 12, carries out exchange heat with the air in the external world, cold-producing medium heat absorption evaporation, the cooled dehumidifying of air.Concrete comprise the second input 121 and the second output 122, second input 121 is communicated with recuperator 23, the second output 122 is communicated with compressor 31 by four-way change-over valve 22.
This recuperator 23 mainly utilizes the air draft of indoor lower temperature to carry out high temperature refrigerant in condensation energy recover, reach the object of condensing units, concrete comprises the 3rd input 231 and the 3rd output 232,3rd input 231 is communicated with air-cooled condenser 32, and the 3rd output 232 is communicated with the second input 121 of evaporimeter 12.Further be communicated with realizing circulating by the second magnetic valve 42 between four-way change-over valve 22 at compressor 31 output.
In the present embodiment, under refrigerating state, first magnetic valve 41 is opened, second magnetic valve 42 cuts out, compressor 31 is communicated with the first input end 131 of the first reheater 13, the refrigerant gas of low-temp low-pressure becomes the refrigerant gas of HTHP by compressor 31, by the first reheater 13, wind pushing air in the refrigerant gas of HTHP and air-supply passage 1 carries out exchange heat, condensation of refrigerant heat release, air themperature raises, send into indoor, cold-producing medium enters air-cooled condenser 32 by four-way change-over valve 22 again, in air-cooled condenser 32 after condensation heat release, again by recuperator 23, exchange heat is carried out in the air draft of the cold-producing medium in recuperator 23 and indoor lower temperature, temperature of outgoing air raises, outside discharge chamber, cold-producing medium exothermic condensation, the liquid of low-temp low-pressure is become after expansion valve 233 reducing pressure by regulating flow, and then flow through evaporimeter 12, the gas of low-temp low-pressure is become after heat absorption evaporation, four-way change-over valve 22 is communicated with again by the second output 122, get back in compressor 31, in compressor 31, cold-producing medium is compressed to the refrigerant gas of HTHP, and carry out next one circulation.
The refrigerant gas of low-temp low-pressure becomes the refrigerant gas of HTHP by compressor 31, by the first reheater 13, wind pushing air in the refrigerant gas of HTHP and air-supply passage 1 carries out exchange heat, condensation of refrigerant heat release, air themperature raises, send into indoor, cold-producing medium enters air-cooled condenser 32 by four-way change-over valve 22 again, in air-cooled condenser 32 after condensation heat release, again by recuperator 23, exchange heat is carried out in the air draft of the cold-producing medium in recuperator 23 and indoor lower temperature, temperature of outgoing air raises, outside discharge chamber, cold-producing medium exothermic condensation, the liquid of low-temp low-pressure is become after expansion valve 233 reducing pressure by regulating flow, and then flow through evaporimeter 12, the gas of low-temp low-pressure is become after heat absorption evaporation, four-way change-over valve 22 is communicated with again by the second output 122, get back in compressor 31, in compressor 31, cold-producing medium is compressed to the refrigerant gas of HTHP, and carry out next one circulation.
It should be noted that, because in air exhaust passage 2, the temperature of indoor exhaust wind is lower, therefore by recuperator 23, the air draft of indoor lower temperature can be used for the condensation of high temperature refrigerant, not only can reduce the condensing pressure of refrigeration system, the refrigerating capacity of unit can also be improved.
Further for improving the heat again to sending into air, on the first input end 131 of the first reheater 13, also parallel connection is provided with the 3rd magnetic valve 43 and the 4th magnetic valve 44; 3rd magnetic valve 43 and the 4th magnetic valve 44 one end all with the first magnetic valve 41 serial communication, the other end is communicated with the input of the second reheater (not shown) with the 3rd reheater (not shown) respectively, and the second reheater is all communicated with four-way change-over valve 22 by check valve 133 with the output of described 3rd reheater.The size of heat coordinates the 3rd magnetic valve 43 and the 4th opening or closing of magnetic valve 44 to control by the first magnetic valve 41 again.When the first magnetic valve 41 is opened, the 3rd magnetic valve 43 closes, and the 4th magnetic valve 44 closes, then heat is 25%; When the first magnetic valve 41 is opened, the 3rd magnetic valve 43 is opened, and the 4th magnetic valve 44 closes, then heat is 50%; When the first magnetic valve 41 is opened, the 3rd magnetic valve 43 closes, and the 4th magnetic valve 44 is opened, then heat is 75%; When the first magnetic valve 41 is opened, the 3rd magnetic valve 43 is opened, and the 4th magnetic valve 44 is opened, then heat is 100%.Certainly in other embodiments, multiple reheater is set according to the actual requirements, and is opened by different solenoid control, realize the control of reheating amount ratio.
In the present embodiment, heating under state, first magnetic valve 41 cuts out, and the second magnetic valve 42 is opened, and compressor 31 is communicated with the second input 121 of evaporimeter 12, it should be noted that, because in air exhaust passage 2, the temperature of indoor exhaust wind is lower, therefore by recuperator 23, the air draft of indoor lower temperature can be used for the condensation of high temperature refrigerant, not only can improve the evaporating pressure of system, reduce the energy consumption of fresh air dehumidification unit, the defrosting number of times of fresh air dehumidification unit can also be reduced.
It should be noted that now, under air-cooled condenser 32 is in off position, just for being communicated with, and the switching on evaporimeter 12 and air-cooled condenser 32 practical function, evaporimeter 12 is now used as condensation heat release.
Because in air exhaust passage 2, temperature of outgoing air is higher, therefore by recuperator 23, the heat making the refrigerant liquid of low-temp low-pressure absorb the higher air draft of indoor temperature evaporates, not only increase the evaporating pressure of heating, also reduce the power consumption of unit, and decrease the defrosting number of times of unit.
In the present embodiment, no matter be under refrigerating state or be all that humiture process is carried out to the new wind that outdoor enters under heating state, owing to containing many powder particle things in outdoor air, so by the new wind entered must in advance after filtration device 11 filter rear reprocessing, the comfort level of indoor environment can be ensured, so concrete filter 11 includes the fly net 111 for preventing mosquito, for the first filter 112 and the second filter 113 of dust granules in filtered air.And room air when getting rid of also in advance by discharging from air exhaust passage 2 after screen pack 21, avoid affect the service life of channel blockage and the recuperator 23 be arranged in passage and exhaust blower 24.Wherein, the first concrete filter 112 and the second filter 113 and fly net 111, and screen pack 21 all commercially has sale, and fly net 111 and screen pack 21 are preferably the nylon material of market at prices material benefit as airstrainer, can need according to concrete filtration to select rational filter, no longer specifically repeat one by one herein.
In the present embodiment, refrigeration and the switching under heating state, and realizing the indispensable parts of circulation yes four-way change-over valve 22, four-way change-over valve 22 comprises the identical ventilating opening of four sizes, is respectively first mouth of pipe 221, second mouth of pipe 222, the 3rd mouth of pipe 223 and the 4th mouth of pipe 224; First mouth of pipe 221 is communicated with the exhaust outlet of compressor 31; Second mouth of pipe 222 is communicated with the second input 121 of evaporimeter 12; 3rd mouth of pipe 223 is communicated with the air entry of compressor 31; 4th mouth of pipe 224 is communicated with air-cooled condenser 32.
