As shown in Figure 1, existing heat pump air conditioner mainly is made up of compressor 1, solenoid operated four-way valve 2, outdoor heat exchanger 3, outdoor fan 4, throttling arrangement 5, indoor heat exchanger 6, indoor fan 7, pipeline 10 etc.Arrow is represented the flow direction of existing air-conditioning cold-producing medium when dehumidification mode moves among the figure, and as seen, this moment, the operation of air conditioner process was as follows: gaseous refrigerant is by the steam of compressor 1 boil down to HTHP; Steam is transported to outdoor heat exchanger 3 through the selection of solenoid operated four-way valve 2 guiding by pipeline 10, the refrigerant cools heat release, becomes the liquid cold-producing medium of HTHP; Liquid refrigerant enters into throttling arrangement 5(such as capillary), after the step-down throttling of throttling arrangement 5, become low-temp low-pressure liquid; Low-temp low-pressure liquid enters indoor heat exchanger 6 again; Liquid refrigerant evaporates becomes low temperature and low pressure steam; Low temperature and low pressure steam comes back to compressor 1, continues circulation next time.Circulation and so forth, cold-producing medium evaporates in indoor heat exchanger and a large amount of heat in the absorbing environmental, indoor heat exchanger will turn cold, indoor fan 7 is blown over indoor air from indoor heat exchanger 6, airborne steam runs into the indoor heat exchanger generation condensation of cooling and is attached to the top and forms the globule, the globule compiles by outside the drainpipe delivery chamber, and room air is able to be dehumidified.
Therefore, existing air-conditioning is the principle of using freeze drying, make low-temperature receiver with cold-producing medium, make cooling device with direct evaporative type cooler (being indoor heat exchanger 6), air is cooled to below the dew-point temperature, separate out the steam greater than saturated water capacity, reduce the absolute moisture content of air, the cooled air of the partly or entirely cold doubtful heat heating of recycling, thus the relative humidity of reduction air reaches the dehumidifying purpose.Existing air-conditioning will reach the dehumidifying purpose, when namely moving under dehumidification mode, will inevitably cause indoor temperature to descend, and is colder when this just causes dehumidifying winter, can't meet consumers' demand.
The utility model content
The problem that the utility model causes indoor temperature to descend when being to solve the air conditioner dehumidification operation is for the dehumidifying in the low temperature and high relative humidity environment provides a kind of better scheme.
For this reason, the utility model provides a kind of air-conditioning with dehumidification function, mainly be made up of compressor, outdoor heat exchanger, outdoor fan, throttling arrangement, indoor heat exchanger, indoor fan, pipeline, controller, it is characterized in that: above-mentioned compressor is frequency-changeable compressor; The arranged outside of above-mentioned indoor heat exchanger has electric heater and temperature sensor; Under air-conditioning was in dehumidification mode, the indoor temperature that controller detects according to temperature sensor was controlled the switch of electric heater and is adjusted the running frequency of frequency-changeable compressor.
Be under the dehumidification mode that indoor temperature that operation and temperature sensor detect reduces gradually and during less than the setting value in the controller at air-conditioning; Controller just can opening electric heater and is turned down the running frequency of compressor.At this moment, indoor heat exchanger is refrigerated dehumidification but refrigerating capacity is lower, simultaneously electric heater produces heat still, and indoor temperature is kept or increases.
If air-conditioning is under the dehumidification mode that indoor temperature that operation and temperature sensor detect raises gradually and when being higher than setting value in the controller, controller just can the temporary close electric heater and is heightened the running frequency of compressor.At this moment, the refrigerated dehumidification effect of indoor heat exchanger strengthens, and indoor temperature is kept or reduces.
Therefore, the air-conditioning of the band dehumidification function of this embodiment can remain on steady temperature, i.e. the operation that dehumidifies of setting value in the controller, the problem that has caused indoor temperature constantly to descend when having solved the air conditioner dehumidification operation is for the dehumidifying in the low temperature and high relative humidity environment provides a kind of better scheme.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is that existing heat pump air conditioner is in the schematic diagram under the dehumidification mode;
