Description
Technical field
The utility model relates to a kind of dehumidifier, relates to a kind of heat pipe defrosting low temperature dehumidification machine in particular.
Background technology
The operating ambient temperature of low form dehumidifier is 5 ~ 32 DEG C, but when dehumidifier works under lower than the environment of 18 DEG C, evaporator surface can frosting, thus affects dehumidifier and normally work.So low form dehumidifier must with defrost function.Existing low form dehumidifier has employing electrical heating defrosting mode, adopts electrical heating defrosting to there will be the phenomenon of local heating's inequality, and need stop compressor, can cause the larger fluctuation of ambient temperature and humidity; Also have and adopt cross valve commutation to heat, make evaporimeter change condenser into, utilize condensation heat to carry out defrosting, unit result of use can be affected owing to often changing refrigeration and heating, and can dehumidification rate be reduced; Also have and adopt hot gas bypass defrosting, but this also can reduce dehumidification rate.
Summary of the invention
The purpose of this utility model is the defect for above-mentioned defrosting mode, provides a kind of heat pipe defrosting low temperature dehumidification machine.
The technical solution of the utility model is: a kind of heat pipe defrosting low temperature dehumidification machine, comprise evaporator fin, compressor, heating power expansion valve, device for drying and filtering, reservoir, fin condenser, centrifugal blower, heat pipe, magnetic valve, wherein, evaporator fin connects compressor, compressor connects fin condenser, fin condenser connects reservoir, reservoir connects device for drying and filtering, device for drying and filtering connects heating power expansion valve, heating power expansion valve connects evaporator fin, fin condenser side is connected with centrifugal blower, it is characterized in that: a heat pipe is set, heat pipe evaporator section is located between fin condenser and centrifugal blower, heat pipe condenser section is located at evaporator fin air intake side, heat pipe evaporator section is connected by adiabatic tube connector with heat pipe condenser section, adiabatic tube connector has installed magnetic valve additional.
The beneficial effects of the utility model are: utilize heat pipe evaporator section absorption condensation heat, and condensation heat is transferred to heat pipe condenser section, heat pipe condenser section is released heat and is used for carrying out preheating to the air entering evaporator fin, improve evaporating temperature, can effectively prevent evaporator fin frosting, and avoid frequent start-stop compressor, improve compressor service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: adiabatic tube connector 83 heat pipe condenser section 9 magnetic valve of 1 evaporator fin 2 compressor 3 heating power expansion valve 4 device for drying and filtering 5 reservoir 6 fin condenser 7 centrifugal blower 8 heat pipe 81 heat pipe evaporator section 82.
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 heat pipe defrosting low temperature dehumidification machine, comprise evaporator fin 1, compressor 2, heating power expansion valve 3, device for drying and filtering 4, reservoir 5, fin condenser 6, centrifugal blower 7, heat pipe 8, magnetic valve 9, wherein, evaporator fin 1 connects compressor 2, compressor 2 connects fin condenser 6, fin condenser 6 connects reservoir 5, reservoir 5 connects device for drying and filtering 4, device for drying and filtering 4 connects heating power expansion valve 3, heating power expansion valve 3 connects evaporator fin 1, fin condenser 6 side is connected with centrifugal blower 7, it is characterized in that: a heat pipe 8 is set, heat pipe evaporator section 81 is located between fin condenser 6 and centrifugal blower 7, heat pipe condenser section 83 is located at evaporator fin 1 air intake side, heat pipe evaporator section 81 is connected by adiabatic tube connector 82 with heat pipe condenser section 83, adiabatic tube connector has installed magnetic valve 9 additional.
When dehumidifier runs at low ambient temperatures, evaporator fin 1 starts frosting, opens solenoid valve 9 when frost layer reaches certain thickness, heat pipe evaporator section 81 inner refrigerant absorption condensation heat enters heat pipe condenser section 83 by adiabatic tube connector 82 afterwards, high temperature refrigerant releases heat to the air preheat entering evaporator fin 1 at heat pipe condenser section 83, improve evaporating temperature, evaporator fin 1 frosting can be avoided, condensed cold-producing medium again can by adiabatic tube connector 82 enter heat pipe evaporator section 81 continue heat absorption carry out the next one circulation.After frost layer is melted, magnetic valve 9 cuts out, and heat pipe 8 does not work, and defrosting process compresses machine 2 runs well, and avoids frequent start-stop compressor, improves compressor service life.
