Detailed description of the invention
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.A kind of dehumidifier, comprises compressor 1, outdoor heat exchanger 2, indoor the first heat exchanger 3, indoor the second heat exchanger 4, cross valve 5 and capillary 6; Described cross valve is communicated with compressor, outdoor heat exchanger, indoor the first heat exchanger, indoor the second heat exchanger respectively; The pipeline of described cross valve and indoor the second heat exchanger 4 and outdoor heat exchanger 2 is provided with magnetic valve 7; Described capillary arranges on the pipeline between outdoor heat exchanger and indoor the second heat exchanger.Pipeline between described indoor First Heat Exchanger and cross valve is provided with connection valve 8.Pipeline between described capillary and indoor the second heat exchanger is provided with connection valve 9.
The circulative metabolism of this invention is divided into two kinds: one, the interior circulation of dehumidifier: that the operation-exhaust outlet by compressor is got rid of the gas of HTHP-enter condenser is cooling-become low temperature high pressure gas-hold back-become the liquid of low-temp low-pressure-become the gas of low-temp low-pressure by the evaporator evaporation compressor that absorbs heat-get back to, and so forth by capillary.Two, dehumidifier outer circulation: the in the situation that of normal boot-strap-operation-malaria by blower fan from air inlet suck-pass through evaporimeter-evaporimeter by airborne water adsorption on aluminium flake-become dry air-process condenser dispel the heat-to blow out from air outlet.
Specific works operational mode of the present invention is as follows:
1, cool-down dehumidification pattern
When indoor temperature and humidity all higher, and indoor refrigeration duty is when larger, system runs on cool-down dehumidification pattern, now, cross valve is not charged, and system is pressed refrigeration modes operation, and indoor the second heat exchanger branch road is that magnetic valve turn-offs, outdoor heat exchanger is condenser, and indoor First Heat Exchanger is equivalent to evaporimeter.Room air, only by indoor First Heat Exchanger cool-down dehumidification, becomes in the air return chamber of low temperature and low humidity.Under this pattern, air quantity or the water yield that can also conditioning chamber external heat exchanger further regulate refrigerating capacity and moisture removal, and refrigerating capacity and moisture removal all rise along with the increase of outdoor heat exchanger air quantity or the water yield.
2, temperature adjusting and dehumidifying pattern
When indoor humidity and humidity load all higher, and indoor refrigeration duty is when smaller, system runs on temperature adjusting and dehumidifying pattern.Now, cross valve is not charged, and system is still pressed refrigeration modes operation, and outdoor heat exchanger and indoor the second heat exchanger are two condensers in parallel, and indoor First Heat Exchanger is equivalent to evaporimeter.Room air by indoor First Heat Exchanger cool-down dehumidification after, undertaken again after heat by partial condensation heat through indoor the second heat exchanger, air returns indoor.Under this pattern, air quantity that can also conditioning chamber external heat exchanger and the water yield regulate the distribution of two condenser heat exchange amounts, further heat again in control room, thus reach the object of controlling indoor air temperature.
3, intensification dehumidification mode
When indoor temperature and humidity load all higher, but when indoor temperature is low and thermic load is smaller, system runs on intensification dehumidification mode.Now cross valve no power, system is pressed refrigeration modes operation, and outdoor heat exchanger branch road is turn-offed by battery valve, and indoor the second heat exchanger is equivalent to condenser, and indoor First Heat Exchanger is equivalent to evaporimeter.Owing to also having high temperature refrigerant to flow through in indoor the second heat exchanger, room air by indoor First Heat Exchanger cool-down dehumidification after, be all used to hot-air again through indoor the second heat exchanger whole condensation heat.Under this pattern, because the refrigerant flow path of outdoor heat exchanger turn-offs, all condensation heat is all born by indoor the second heat exchanger, and system condensing heat is greater than heat of evaporation, so processed air humidity decline temperature rise.
4, heating mode
When indoor temperature very low, and thermic load is when larger, although relative humidity is higher, but water capacity is lower, remove airborne moisture more difficult, but by after air heat, in the constant situation of water capacity, the relative humidity of air just declines rapidly, and therefore problem, by system heating operation, realizes the control to indoor temperature and humidity.Now, cross valve is charged, and system is moved by the mode of heating, and indoor the second heat exchanger is turn-offed by magnetic valve, and outdoor heat exchanger is equivalent to evaporimeter, and indoor First Heat Exchanger is equivalent to condenser.Under this pattern, room air by the heating of indoor First Heat Exchanger after, after indoor the second heat exchanger does not carry out heat exchange in return chamber.The temperature rise of air like this, humidity decline, thereby realize the control to indoor temperature and humidity.
5, automatic defrosting
In the time of system running pattern 1-3, indoor First Heat Exchanger is equivalent to evaporimeter, when evaporator surface temperature is during lower than 0 degree Celsius, airborne moisture may be in evaporator external frosting, when frost reaches after certain thickness, make the air side pressure loss increase, air mass flow reduces, heat transfer effect is poor, need to defrost.Now, make unit operation heat damping pattern, indoor First Heat Exchanger is as condenser, and entering of high temperature refrigerant makes, after the rapid thawing of frost, to recover original operational mode.
In the time that system runs on heating mode 4, outdoor heat exchanger is equivalent to evaporimeter, when outside air temperature low humidity is high and evaporator surface temperature during lower than 0 degree Celsius, the also possibility frosting of outdoor heat exchanger outer surface, when frost reaches after certain thickness, make unit operation in temperature adjusting and dehumidifying pattern, outdoor heat exchanger is as condenser, high temperature refrigerant melts rapidly frost, indoor the second heat exchanger is also as condenser, prevent that the air of being lowered the temperature by indoor First Heat Exchanger from directly entering indoor, after frost is removed completely, recover to heat temperature adjustment pattern.
The invention provides a kind of can be to the indoor dehumidification equipment that carries out heat supply, refrigeration and dehumidifying at the inside and outside temperature of different chamber, the present invention has that cool-down dehumidification, temperature adjusting and dehumidifying, intensification dehumidify, heat, automatic defrosting operational mode; The present invention is regulating refrigerating capacity, heating capacity and moisture removal by operational mode conversion, under every kind of operational mode, can also adjust rotation speed of fan and the pump rotary speed of outdoor heat exchanger to adjust the heat distribution between outdoor heat exchanger and indoor heat exchanger, refrigerating capacity and heating capacity to system are finely tuned, to improve the degree of regulation of humiture; Because the present invention has plurality of operating modes, can realize refrigeration in a big way, the adjustable range that heats, dehumidifies, outdoor heat exchanger can adopt the forms such as air-cooled or water-cooled, can use in different regions.
