Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Present embodiment provides a kind of heat reclamation energy-saving-type constant temperature and humidity unit, and structure comprises interior machine 1 and outer machine 2 as shown in Figure 1.Described interior machine 1 is comprised of evaporimeter 3, centrifugal blower 4, heat recovery heat exchange device 5 and water storage device 6, and described outer machine 2 is comprised of condenser 7, compressor 8 and radiator fan 9.
Described heat recovery heat exchange device 5 is located between evaporimeter 3 and the centrifugal blower 4.The inlet of described heat recovery heat exchange device 5 is connected by compressor 8 with the water side of condenser 7, and the liquid outlet of heat recovery heat exchange device 5 links to each other with water storage device 6.The water side of described water storage device 6 links to each other by copper pipe with the water inlet end of condenser 7.Described condenser 7, compressor 8 connect and compose refrigeration system by copper pipe.Be provided with electric control valve 10 between described heat recovery heat exchange device 5 and the water storage device 6.Described electric control valve 10 is two logical or triple valves.Described heat recovery heat exchange device 5 adopts the dual coil pipes design, can lead to simultaneously hot water and cold water.
Refrigerated dehumidification principle of the present utility model is: the high-temperature high-pressure refrigerant gas that compressor 8 is discharged enters condenser 7, be condensed into middle temperature highly pressurised liquid, and enter evaporimeter 3 by the vapour-liquid two-phase mixture that becomes low-temp low-pressure behind the reducing pressure by regulating flow, vapour-liquid two-phase mixture evaporimeter 3 interior absorptions flow through evaporimeter 3 the air heat and evaporate, the air of the evaporimeter 3 of flowing through is lowered the temperature, because evaporimeter 3 fin surface temperature are lower than the dew-point temperature of air, air stream is when evaporimeter 3 surface, there is moisture content to separate out on evaporimeter 3 surfaces, air absolute humidity through evaporimeter 3 reduces, and reaches simultaneously the dehumidifying purpose.Sucked by compressor 7 again after the cold-producing medium heat absorption vaporization, sent by centrifugal blower 4 behind new wind process evaporimeter 3 cool-down dehumidifications.
