Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of air energy high-temperature dehumidification heat pump leaf drier as shown in Figure 1, comprise casing 12 and be placed in the compressor 1 of casing 12 inside, casing 12 is provided with air inlet 10, air outlet 11, outer circulation air inlet 7 and outer circulation fan outlet 13, is provided with sensible heat exchanger 3, supplementary heat exchanger 2, interior heat exchanger 8 and Inner eycle blower fan 9 between air inlet 10 and air outlet 11 successively; Outer circulation blower fan 5 and external heat exchanger 6 is provided with successively between outer circulation air inlet 7 and outer circulation fan outlet 13; Also be provided with circuit control module 4 in casing 12, this circuit control module 4 is electrically connected with described compressor 1, outer circulation blower fan 5, Inner eycle blower fan 9, interior heat exchanger 8, external heat exchanger 6, supplementary heat exchanger 2 and sensible heat exchanger 3 respectively.Inner eycle blower fan 9 is centrifugal fan, adopts centrifugal type efficient blower fan, namely ensure that the air quantity of baking needed further provides enough pressure heads, improve the horizontal temperature difference in baking room and vertical temperature-difference to greatest extent.Supplementary heat exchanger 2, interior heat exchanger 8 and external heat exchanger 6 is fin-tube heat exchanger.Supplementary heat exchanger 2, between interior heat exchanger 8 and external heat exchanger 6, be also connected with control valve and cross valve.
Principle of the present utility model is: utilize inverse Carnot's principle, absorb the heat of air and transferred in storehouse, and the temperature realizing baking room improves, and coordinates corresponding equipment to realize the drying of material.Heat pump drier constitutes a circulatory system by devices such as compressor-condenser-evaporimeter-compressors.Refrigerant under the effect of compressor at system internal circulation flow, it completes the boosting temperature-rise period (temperatures as high 100 DEG C) of gaseous state in compressor, it enters condenser and discharges air in heat of high temperature heating, drying room, oneself be cooled and be converted into liquid state simultaneously, the liquid coolant of low-temp low-pressure is converted into through the throttling action of restricting element, after being circulated to evaporimeter, heat absorption evaporation is converted into gaseous state again rapidly, and at this moment the air of periphery will transfer heat to refrigerant continuously.Refrigerant constantly circulates and heats air themperature in room with regard to realizing the heat in air to be transported in baking room.
The course of work of the present utility model, as shown in Figure 2, this air energy high-temperature dehumidification heat pump leaf drier is connected with baking room 15 by circulation air path 14.In baking room 15, the sensible heat exchanger 3 of hot and humid air in the A place access arrangement of air inlet 10 flows to B place, supplementary heat exchanger 2 is entered from C, then sensible heat exchanger 3 is entered from D, out enter interior heat exchanger 8 from E to heat, deliver into baking room 15 through Inner eycle blower fan 9, thus form Inner eycle; Air in external environment enters in casing 12 from outer circulation air inlet 7, under the effect of circulating fan 5 outside, flows through external heat exchanger 6, blows out from outer circulation fan outlet 13, thus forms outer circulation.
Baking room 15 high temperature return air, Exchange of apparent heat is made when flowing through A-B place with when supplementary heat exchanger 2 Cryogenic air out flows through D-E, heat is delivered to D-E flow process from A-B flow process, reduce the air themperature entering supplementary heat exchanger 2 on the one hand, thus improve its relative humidity, can the dehumidification rate of remarkable elevator system; On the other hand, absorb part again from supplementary heat exchanger 2 Cryogenic air out through the sensible heat of D-E flow process and improve leaving air temp, improve the heating efficiency of whole system.In addition connection control valve can also be passed through between these three heat exchangers of supplementary heat exchanger 2, interior heat exchanger 8 and external heat exchanger 6, cross valve, changement etc., the various combination carried out switches control, run various modes, realize the several functions such as refrigeration cool-down, heat pump intensification, constant temperature dehumidification, cool-down dehumidification, intensification dehumidifying.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
