The specific embodiment
Referring to Fig. 2, the utility model design feature is: the prior art of Fig. 1 is connected to change into the indoor electric expansion valve EVI6 of second heat exchanger 8 and liquid pipe 2 is connected first heat exchanger 10 and corresponding liquid pipe 2, while increase between second heat exchanger 8 and liquid pipe 2 has magnetic valve D13.Indoor electric expansion valve EVI6 and described magnetic valve D13 are connected in parallel, thereby constitute cooling/heating system as shown in Figure 2.
The action of each parts such as following table during the utility model operating condition:
Temperature adjusting and dehumidifying procedure declaration of the present utility model is as follows.
The utility model utilizes indoor electric expansion valve EVI6 to be connected between first heat exchanger 10 and the liquid pipe 2, just can regulate the height of wind pushing temperature by the aperture size of electric expansion valve EVI6 in the conditioning chamber.
Concrete adjustment process is as follows:
A, when indoor electric expansion valve EVI6 closes fully, its regulative mode is similar to the prior art scheme, refrigerant all enters second heat exchanger 8 behind magnetic valve D13, all enter first heat exchanger 10 after capillary 12 throttlings again.Room air carries out heat exchange with second heat exchanger 8 and heats up earlier through behind first heat exchanger, 10 cool-down dehumidifications, has improved wind pushing temperature like this.Wind pushing temperature in this case can be higher than return air temperature, promptly is the function that can reach the dehumidifying that heats up;
When b, indoor electric expansion valve EVI6 open certain aperture, under magnetic valve D13, second heat exchanger 8 and capillary 12, the magnetic valve B9 situation in parallel with indoor electric expansion valve EVI6, the coolant quantity that enters second heat exchanger 8 reduces, and the coolant quantity that enters first heat exchanger 10 increases during than above-mentioned a process.Room air is same earlier through behind first heat exchanger, 10 cool-down dehumidifications, carrying out heat exchange with second heat exchanger 8 again heats up, but the more above-mentioned a process of coolant quantity that enters second heat exchanger 8 because of this moment is few, wind pushing temperature can be more lower slightly than above-mentioned a process under identical situation, the height that so just can change wind pushing temperature reaches isothermal dehumidifying or cool-down dehumidification, and in this process by feedback circuit 16 and 17 for indoor electric expansion valve EVI6 provides conditioning signal, the comparison circuit 17 that the actual humidity of comparison circuit 16 that the actual temperature that described feedback circuit is obtained by sensor for measuring temperature is compared with target temperature and the acquisition of moisture measurement sensor is compared with target humidity is formed.
The refrigerating operaton process: cross valve 3 actions, magnetic valve B9, D13 closes, magnetic valve A7, C11 opens, the indoor and outdoor fan running.The gas of the HTHP of discharging from compressor 1 is through behind the cross valve 3, the 4 condensation heat releases of inlet chamber outer heat-exchanger, behind outdoor expansion valve EVOS, after indoor expansion valve EVI6 throttling step-down cooling, become the liquid refrigerants of low-pressure low-temperature, enter the gaseous coolant of first heat exchanger 8 and second heat exchanger 10 evaporation heat absorptions the becoming low-pressure low-temperature more simultaneously, and carry out heat exchange to reduce the temperature of room air with room air, get back to compressor 1 through cross valve 3 then, and in this process by feedback circuit 16 and 17 for indoor electric expansion valve EVI6 provides conditioning signal, the comparison circuit 17 that the actual humidity of comparison circuit 16 that the actual temperature that described feedback circuit is obtained by sensor for measuring temperature is compared with target temperature and the acquisition of moisture measurement sensor is compared with target humidity is formed.
But the method for operating of temperature adjusting and dehumidifying: but when air-conditioner carried out the temperature adjusting and dehumidifying operation, cross valve 3 was opened, magnetic valve B9, D13 opens, magnetic valve A7, C11 closes, and indoor electric expansion valve EVI6 can regulate aperture.Throttle capillary tube 12 plays the throttling hypotensive effect, outdoor fan low cruise or stall, indoor fan running.The gas of the HTHP of discharging from compressor 1 is through behind the cross valve 3, inlet chamber outer heat-exchanger 4 carries out partial condensation, refrigerant is shunted according to the aperture size of indoor expansion valve EVI6 when the indoor: wherein a part is carried out the condensation heat release by entering second heat exchanger 10 behind the magnetic valve D, becomes the gaseous coolant of low-temp low-pressure afterwards again through capillary 12 throttling step-downs cooling; Another part then becomes the gaseous coolant of low-pressure low-temperature by throttling step-down cooling behind the indoor expansion valve EVI6, enter first heat exchanger 8 simultaneously after above-mentioned two parts refrigerant mixes and evaporate heat absorption, become the liquid refrigerants of low-pressure low-temperature, get back to compressor 1 through cross valve 3 then.Room air then at first carries out heat exchange with first heat exchanger 10 and carries out cool-down dehumidification, and then carries out heat exchange with second heat exchanger 8 and heat up to improve wind pushing temperature.The adjusting of wind pushing temperature mainly is that the aperture size by indoor electric expansion valve EVI6 has changed the heat exchange amount size with first, second heat exchanger, thereby regulated the height of wind pushing temperature, and in this process by feedback circuit 16 and 17 for indoor electric expansion valve EVI6 provides conditioning signal, the comparison circuit 17 that the actual humidity of comparison circuit 16 that the actual temperature that described feedback circuit is obtained by sensor for measuring temperature is compared with target temperature and the acquisition of moisture measurement sensor is compared with target humidity is formed.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
