The utility model has following remarkable result:
Compared to existing technology, the utility model, on normal cold/hot air-conditioning function basis, can make room dehumidification air conditioner have refrigeration, the heat-production functions of traditional rooms air-conditioner, have dehumidification function again, and when can guarantee dehumidifying, room temperature does not decline.
The utility model design is simple and clear, structure simple, good manufacturability, except indoor set and off-premises station adopt except three copper pipes are connected, other with traditional rooms air-conditioner profile and volume quite, use also very convenient.This utility model, on the basis not affecting air-conditioner refrigeration and heating performance, can also realize temperature adjusting and dehumidifying function, and not increase the volume of indoor apparatus of air conditioner.
Accompanying drawing explanation
Fig. 1 is the systematic schematic diagram of temp. controllable dehumidification air conditioner.
Detailed description of the invention
Below in conjunction with accompanying drawing with by example, the utility model is further described.
See Fig. 1, a kind of room dehumidification air conditioner, compressor 1, indoor heat exchanger 2, throttle capillary tube 3 (the 3rd throttle capillary tube 33 comprising first throttle capillary 31, second throttle capillary tube 32 and connect with the one the second throttle capillary tubes is comprised by part, also the 3rd throttle capillary tube 33 can not be adopted to connect), outdoor heat exchanger 4, electromagnetism four-way change-over valve 5, first control valve 6, second control valve 7 form, wherein indoor heat exchanger is divided into First Heat Exchanger 21 and 22 two sections, the second heat exchanger by the first capillary 31 and the second capillary 32 pipe.The selection of throttle capillary tube parameter is identical with existing air-conditioning equipment.
Below further illustrate the dehumidification control method that the dehumidification air conditioner shown in Fig. 1 adopts.
The utility model realizes dehumidification function method: solenoid operated four-way valve 5 is in refrigeration mode (connecting as shown in dotted line in Fig. 1 cross valve 5), control valve 7 is opened, control valve 6 is closed, the refrigerant gas of the HTHP that compressor 1 exports flows through the condensation segment 22 that solenoid operated four-way valve enters outdoor heat exchanger 4 and indoor heat exchanger respectively, after condensation, after highly pressurised liquid converges respectively by throttle capillary tube 33 and 32, step-down is continued again through throttle capillary tube 31, enter indoor heat exchanger 21 to evaporate, the refrigerant vapour of low-temp low-pressure gets back to compressor 1 by solenoid operated four-way valve 5, complete kind of refrigeration cycle.While realizing this kind of refrigeration cycle, indoor humid air is cool-down dehumidification in evaporimeter 21, reheating in condenser 22, thus realizes the function of dehumidifying.
The method that the utility model realizes temperature adjustment is: realizing desiccant cooling circulation time, serves as indoor heat exchanger condensation segment 22 and outdoor heat exchanger 4 parallel running of condenser, by changing the air quantity of outdoor heat exchanger blower fan, can regulate room air temperature.When the fan delivery of outdoor heat exchanger reduces, the high-temperature refrigeration steam flow flowing through outdoor condenser 4 reduces, and the temperature refrigerant vapor flow flowing through indoor condensation segment 22 increases, room air temperature is raised, otherwise, when outdoor heat exchanger fan delivery strengthens, room air temperature will be declined.
When room thermic load is larger (not at this moment being moist operating mode), if still adopted except wet cooling condition, room air temperature will raise under the effect of room condensation segment 22, usual program setting its higher than setting value 2 DEG C, just proceed to refrigeration mode.
