The dehumidification principle of air-conditioning: open compressor, the dehumidifying effect when utilizing refrigeration (in other words, in process of refrigerastion, the dehumidifying effect that invariably accompanies), airborne condensate moisture, condense into water, and be discharged to sewer.After the reason reduction of air themperature, need utilize electric heater unit to carry out thermal compensation usually because of dehumidifying.Therefore the air-conditioning unit need be opened refrigeration system and electrical heating bucking-out system simultaneously in dehumidification process, and energy loss is very big.
The utility model content
Technical problem to be solved in the utility model is: a kind of dual system air-conditioning unit is provided, to solve the air-conditioning unit in dehumidification process, need opens refrigeration system and electrical heating bucking-out system simultaneously, the technical problem that energy loss is big.
For solving the problems of the technologies described above, the technical solution of the utility model is: dual system air-conditioning unit, comprise cabinet, and described cabinet is provided with air inlet and air outlet; Filter, described filter is corresponding with described air inlet position; It is interior and corresponding with described air outlet position that blower fan, described blower fan are fixedly installed in described cabinet; Cooling cycle system, described cooling cycle system comprise first compressor, first air-cooled condenser, first expansion valve and first evaporimeter that connects by pipeline; Described dual system air-conditioning unit also comprises heat pump circulating system, and described heat pump circulating system comprises second compressor, second air-cooled condenser, four-way change-over valve, second expansion valve and second evaporimeter that connects by pipeline.
As a kind of improvement, described first evaporimeter is divided into first evaporation section and second evaporation section, also is provided with on the pipeline of described cooling cycle system to make described first expansion valve select with described first evaporation section and second evaporation section is communicated with simultaneously or the dehumidifying valve that only is communicated with one of them evaporation section.
As a kind of improvement, described dehumidifying valve is a magnetic valve.
As a kind of improvement, described dual system air-conditioning unit also comprises damping device, and it is interior and corresponding with the entrance location of described blower fan that described damping device is fixedly installed in described cabinet.
Owing to adopted technique scheme, the beneficial effects of the utility model are: because dual system air-conditioning unit is provided with cooling cycle system and heat pump circulating system, when cooling, the two cover circulatory systems are freezed simultaneously or are selectively freezed, and have heightened refrigerating efficiency; When dehumidifying, the cooling cycle system cool-down dehumidification, heat pump circulating system changes the loop direction of heat-exchange working medium by four-way change-over valve, room air is carried out heat compensation, compare with electrical heating, reduced energy consumption, for example: if produce the 3KW heat, use electric heater, then need to consume the electrical power of 3KW; If the employing heat pump assembly, only needs consume the electrical power of about 1KW, just can produce the heat of 3KW by the heat exchange of heat-exchange working medium.
Because first evaporimeter is divided into first evaporation section and second evaporation section, also be provided with on described first evaporimeter and make first expansion valve select and second evaporation section is communicated with simultaneously or the dehumidifying valve that only is communicated with one of them evaporation section with described first evaporation section, during dehumidifying, dehumidifying valve closing part disengagement area, refrigeration has weakened, strengthen effect on moisture extraction, made required heat compensation reduce simultaneously, saved the energy.
Owing to be provided with damping device in the cabinet, make dual system air-conditioning unit possess dehumidifying and humidification function, can under robot control system(RCS) control, realize constant temperature and humidity, use more extensive.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, cabinet, 2, blower fan, 3, first evaporimeter, 4, dehumidifying valve, 5, first expansion valve, 6, first air-cooled condenser, 7, filter, 8, first compressor, 9, second compressor, 10, second air-cooled condenser, 11, four-way change-over valve, 12, second expansion valve, 13, second evaporimeter, 14, damping device.
The specific embodiment
As shown in drawings, a kind of dual system air-conditioning unit comprises cabinet 1, and described cabinet 1 is provided with air inlet and air outlet; Filter 7, described filter 7 is corresponding with described air inlet position; Blower fan 2, described blower fan 2 are fixedly installed in the described cabinet 1 and are corresponding with described air outlet position; Cooling cycle system, described cooling cycle system comprise first compressor 8, first air-cooled condenser 6, first expansion valve 5 and first evaporimeter 3 that connects by pipeline; Described dual system air-conditioning unit also comprises heat pump circulating system, and described heat pump circulating system comprises second compressor 9, second air-cooled condenser 10, four-way change-over valve 11, second expansion valve 12 and second evaporimeter 13 that connects by pipeline.
Described first evaporimeter 3 is divided into first evaporation section and second evaporation section, also is provided with on the pipeline of described cooling cycle system to make described first expansion valve 5 select with described first evaporation section and second evaporation section is communicated with simultaneously or the dehumidifying valve 4 that only is communicated with one of them evaporation section.Described dehumidifying valve 4 is a magnetic valve.
Described dual system air-conditioning unit also comprises damping device 14, and described damping device 14 is fixedly installed in the described cabinet 1 and is corresponding with the entrance location of described blower fan 2.
Its course of work is as follows:
The air-conditioning unit generally comprises robot control system(RCS), blower fan, refrigeration system and heating system, and the utility model comprises cooling cycle system and heat pump circulating system.
During refrigeration, cooling cycle system and heat pump circulating system freeze simultaneously.The heat-exchange working medium (for example gaseous fluorine Leon) of the HTHP that first compressor 7 is discharged enters first air-cooled condenser 6, lower the temperature by outdoor air, then by after first expansion valve, the 5 rapid decrease temperature and pressure, become the liquid state of low-temp low-pressure, enter first evaporimeter 3, carry out heat exchange with room air, return first compressor 7, form the cooling cycle system refrigeration.The heat-exchange working medium (for example gaseous fluorine Leon) of the HTHP that second compressor 9 is discharged enters second air-cooled condenser 10, lower the temperature by outdoor air, enter second expansion valve 12 through four-way change-over valve 11, after second expansion valve, 12 rapid decrease temperature and pressure, enter second evaporimeter 13, carry out heat exchange with room air, return second compressor 9, form the heat pump circulating system refrigeration.
During dehumidifying, start the kind of refrigeration cycle circulation, evaporimeter 3 surface temperatures of winning are sharply descended, when temperature is lower than the dew-point temperature of current working, airborne steam will condense soon, and be discharged in the sewer by drainpipe.In order to make the dehumidifying effect strengthen, generally adopt a special dehumidifying valve 4 to close the area of a part of evaporimeter, make evaporating temperature further reduce, help strengthening dehumidifying, the reduction cooling.Dehumidifying is accompanied by cooling, and heat pump circulating system carries out heat compensation by the loop direction of four-way change-over valve 11 change heat-exchange working mediums to room air, has saved the energy.
