Background technology
At present, plain edition dehumidifier operating ambient temperature is 18 ~ 32 DEG C, and when dehumidifier works under lower than the environment of 18 DEG C, evaporator surface temperature can the frosting lower than 0 DEG C, makes dehumidifier cisco unity malfunction.The operating ambient temperature of low form dehumidifier is 5 ~ 32 DEG C, so low form dehumidifier must with defrost function.Existing low form dehumidifier mainly adopts following defrosting method: one is adopt electrical heating defrosting mode, adopt electric heating tube or heat tape can produce uneven phenomenon of being heated, thus affect defrosting effect, and also need during defrosting to stop compressor, such frequent start-stop compressor, can affect again compressor service life; Another kind method adopts cross valve commutation to heat, and makes evaporimeter change condenser into, utilize condensation heat to carry out defrosting, can affect unit result of use, and can reduce dehumidification rate owing to often changing refrigeration and heating.
Summary of the invention
The purpose of this utility model is the defect for above-mentioned defrosting mode, provides a kind of novel defrosting low temperature dehumidification machine, can dehumidify again while effective defrosting.
The technical solution of the utility model is: a kind of novel defrosting low temperature dehumidification machine, it mainly comprises evaporator fin, compressor, check valve, heating power expansion valve, device for drying and filtering, fluid reservoir, fin condenser, centrifugal blower, magnetic valve, temperature controller, fin temperature sensor, defrosting coil pipe.Wherein, compressor, fin condenser, reservoir, device for drying and filtering, heating power expansion valve, check valve, evaporator fin connect successively, and evaporator fin is connected to compressor, as refrigerating circuit, magnetic valve one end is connected with the import of defrosting coil pipe, the magnetic valve other end is connected to compressor air-discharging end, defrosting coil outlets is connected between one-way valved outlet and evaporator fin import, as defrosting branch road, defrosting coil pipe interts in evaporator fin, fin condenser side is connected with centrifugal blower, fin temperature sensor is fixed on the fin of evaporator fin, and be connected with temperature controller signal input part, temperature controller signal output part is connected with solenoid control end, it is characterized in that: cold-producing medium flow direction in evaporator fin and defrosting coil pipe is contrary, and the reverse flow of cold-producing medium is prevented by arranging check valve.
The beneficial effects of the utility model are: intert in evaporator fin by defrosting coil pipe, the refrigerant gas of compressor air-discharging end HTHP is utilized to flow through defrosting coil pipe, come evaporator fin defrosting by the heat radiation of high-temperature high-pressure refrigerant gas, low-temperature refrigerant after exothermic condensation enters evaporator fin together with the cold-producing medium after throttling, owing to arranging check valve before thermal expansion valve outlet port, the reverse flow of cold-producing medium can be prevented, in defrosting process, compressor is not shut down, proceed dehumidifying, like this, can effectively defrosting, do not affect effect on moisture extraction again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 evaporator fin 2 compressor 3 check valve 4 heating power expansion valve 5 device for drying and filtering 6 reservoir
7 fin condenser 8 centrifugal blower 9 magnetic valve 10 temperature controller 11 fin temperature sensor 12 defrosting coil pipes.
Detailed description of the invention
Specifically implement to be further described to the utility model below in conjunction with accompanying drawing:
With reference to figure 1, described in the utility model is a kind of novel defrosting low temperature dehumidification machine, it mainly comprises evaporator fin 1, compressor 2, check valve 3, heating power expansion valve 4, device for drying and filtering 5, fluid reservoir 6, fin condenser 7, centrifugal blower 8, magnetic valve 9, temperature controller 10, fin temperature sensor 11, defrosting coil pipe 12, wherein, compressor 2, fin condenser 7, reservoir 6, device for drying and filtering 5, heating power expansion valve 4, check valve 3, evaporator fin 1 connect successively, evaporator fin 1 is connected to compressor 2, as refrigerating circuit, magnetic valve 9 one end is connected with defrosting coil pipe 12 import, magnetic valve 9 other end is connected to compressor 2 exhaust end, defrosting coil pipe 9 outlet is connected to check valve 3 and exports between evaporator fin 1 import, as defrosting branch road, defrosting coil pipe 12 interts in evaporator fin 1, fin condenser 7 side is connected with centrifugal blower 8, fin temperature sensor 11 is fixed on the fin of evaporator fin 1, and be connected with temperature controller 10 signal input part, temperature controller 10 signal output part is connected with magnetic valve 9 control end, it is characterized in that: cold-producing medium flow direction in evaporator fin 1 and defrosting coil pipe 12 is contrary, and the reverse flow of cold-producing medium is prevented by arranging check valve 3.
When dehumidifier runs at low ambient temperatures, evaporator fin 1 meeting frosting, when frost layer has certain thickness, the fin temperature experienced is defeated by temperature controller 10 by fin temperature sensor 11, temperature controller 10 exports the signal of telecommunication to magnetic valve 9, magnetic valve 9 is opened, part high-temperature high-pressure refrigerant gas enters defrosting coil pipe 12 through magnetic valve 9, come evaporator fin 1 defrosting by the heat radiation of high-temperature high-pressure refrigerant gas, low-temperature refrigerant after exothermic condensation enters evaporator fin 1 together with the cold-producing medium after throttling, owing to arranging check valve 3 before heating power expansion valve 4 exports, the reverse flow of cold-producing medium can be prevented, in defrosting process, compressor 2 is not shut down, proceed dehumidifying, air is centrifuged blower fan 9 and sucks, through evaporator fin 1, lowered the temperature by after low-temperature low-pressure refrigerant heat absorption and separate out condensate water, then send after fin condenser 7 heats, reach effect on moisture extraction.
