Abstract
The invention relates to an enthalpy-compensating auxiliary defroster of a heat pump water heater, which is used in a defrosting system of the heat pump water heater. The auxiliary defroster comprises a sealed shell, a steel pipe, a first connector and a second connector, wherein a sealed cavity is formed in the sealed shell; the steel pipe comprises a first pipe body, a second pipe body and a third pipe body; two ends of the second pipe body are communicated with the first pipe body and the third pipe body respectively; the second pipe body is positioned in the sealed cavity; the first pipe body and the third pipe body are positioned outside the sealed shell; and the first connector and the second connector are arranged on the sealed shell and are communicated with the sealed cavity. The enthalpy-compensating auxiliary defroster of the heat pump water heater has a reasonable structural design and can improve the defrosting effect of the defrosting system.
Description
Technical field
The present invention relates to a kind of Teat pump boiler and mend the auxiliary defroster of enthalpy, be used for the defrosting system of Teat pump boiler.
Background technology
The defrosting system of Teat pump boiler can be than low under the normal temperature at low temperature situation lower compression acc power, and its delivery temperature is lower, and evaporating temperature is also corresponding lower in the system, finally can cause unit to heat reduction, and the defrost effect is general.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing above-mentioned shortcoming in the prior art, and a kind of reasonable in design is provided, the Teat pump boiler that can improve Teat pump boiler defrosting system defrost effect mends the auxiliary defroster of enthalpy.
The present invention addresses the above problem the technical scheme that is adopted: a kind of Teat pump boiler is mended the auxiliary defroster of enthalpy, it is characterized in that: comprise seal casinghousing, steel pipe, a joint and No. two joints; Form annular seal space in the seal casinghousing; Steel pipe comprises a body, No. two bodys and No. three bodys, and the two ends of No. two bodys are connected with a body and No. three bodys respectively, and No. two body is arranged in annular seal space, and a body and No. three bodys are positioned at outside the seal casinghousing; A joint and No. two joints are installed on the seal casinghousing, and all connect with annular seal space.
No. two bodys of the present invention are spirality.
The present invention is fixed with heat-insulation layer on described seal casinghousing inwall.
The present invention is equipped with check valve on a described body, on described No. three bodys the electromagnetism two-port valve is installed.
The present invention compared with prior art has the following advantages and effect: 1, reasonable in design; 2, can improve the defrost effect of defrosting system.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the schematic side view of Fig. 1.
Fig. 3 is the cross-sectional schematic of the A-A of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1～Fig. 3, the embodiment of the invention comprises seal casinghousing 1, steel pipe 2, a joint 3 and No. two joints 4.
Form annular seal space 5 in the seal casinghousing 1.Be fixed with heat-insulation layer 6 on seal casinghousing 1 inwall, heat-insulation layer 6 surrounds annular seal space 5.
Steel pipe 2 comprises that the two ends of body 21, No. two bodys 22 and 23, No. two bodys 22 of No. three bodys connect with a body 21 and No. three bodys 22 respectively.No. two bodys 22 are arranged in 5, numbers bodys 21 of annular seal space and No. three bodys 23 are positioned at outside the seal casinghousing 1.On a body 21, check valve 7 is installed, on No. three bodys 23, electromagnetism two-port valve 8 is installed.No. two body 22 is a spirality.
A joint 3 and No. two joints 4 are installed on the seal casinghousing 1, and all connect with annular seal space 5.
During use, present embodiment is installed in the defrosting system.No. two body 22 is connected with compressor, and No. three body 23 is connected with separator, and No. two joint 4 is connected with water-to-water heat exchanger.Electromagnetism two-port valve 8 is connected with the control system of Teat pump boiler, the control of controlled system.
Spend when low when matching used unit control system detects return air temperature, send instruction electromagnetism two-port valve 8 is opened, No. two joint 4 inserts hot water from water-to-water heat exchanger, makes hot water be full of whole annular seal space 5.No. three body 23 inserts refrigerant from separator, delivers in No. two bodys 22.Refrigerant absorbs the heat of hot water in No. two bodys 22, makes liquid refrigerant vaporization, and No. two body 22 is a spirality, makes that the refrigerant heat exchanger time is longer, better effects if.The refrigerant of vaporization enters compressor by No. two bodys 22 subsequently.Hot water can be discharged by joint 3, and these hot water can be used for having a bath etc.
When control system detects suction temperature and evaporating temperature and reaches setting value, send instruction, impel electromagnetism two-port valve 8 closures, disconnect refrigerant and the transmission of hot water heat.Check valve 7 guarantees that refrigerant can not reflux.
The present invention utilizes the heat of high temperature of source pump water side water and the preceding refrigerant of low temperature refrigerant of compressor return air port to carry out heat exchange; can improve its suction temperature effectively; guarantee that the no liquid refrigerant enters compressor; when preventing by liquid hammer, the protection compressor improves the compression exhaust temperature; drive the raising of evaporator temperature; cause system's frosting phenomenon to diminish, cause system's defrost effect to be improved effectively, in 0～10 ° of C scope, can suppress the appearance of frosting phenomenon.The rising of delivery temperature drives compression horsepower and promotes, effective elevator system enthalpy, the heating capacity of overall improved system and efficient.
