Description
Technical field
This utility model is related to a kind of heating equipment, and in particular to a kind of antifrost hot-water heating system.
Background technology
At present, low-temperature heat pump water heater is to say in recent years the New-type water heater favored that becomes, and which uses inverse Carnot's principle, with few
Electric energy, substantial amounts of low temperature heat energy in absorption air is changed into high temperature heat by the compression of compressor, transmits to water tank, heating
Hot water, so its energy consumption is low, efficiency high, speed is fast, safety is good, the feature of environmental protection is strong, endlessly hot-water supply.As hot water
System it there is to be difficult analogy.But current low-temperature heat pump water heater generally existing vaporizer defrosting effect is poor
Problem, when vaporizer work under the operating mode of severe cold can faster frosting, defrosting effect difference can be easier to cause evaporimeter frosting to be asked
Topic effectively causes failure.
Utility model content
For the deficiencies in the prior art, this utility model aims to provide a kind of antifrost hot-water heating system, by from connection storage
Flow container directly connects the vaporizer with a branch line is separated in the pipeline of plate type heat exchanger, then can realize changing through board-like
Coolant after hot device has lead directly to all the way vaporizer, plays the defrosting effect of vaporizer using the waste heat of coolant, so as to strengthen
The defrosting effect of vaporizer.
To achieve these goals, this utility model is adopted the following technical scheme that：
A kind of antifrost hot-water heating system, including compressor, cross valve, plate type heat exchanger, fluid reservoir and vaporizer, the pressure
The inlet and outlet of contracting machine, the plate type heat exchanger, vaporizer are respectively communicated with the cross valve, and the fluid reservoir is communicated in institute
Plate type heat exchanger is stated, and the vaporizer is communicated in by expansion valve；The plate type heat exchanger is respectively communicated with entering in a water pump
Mouth and outlet；A branch line is communicated with the pipeline for connecting the fluid reservoir and plate type heat exchanger, the branch line is straight
The vaporizer is passed through in succession；Direction on the branch line toward the vaporizer is sequentially provided with check valve and two-port valve.
Used as a kind of preferred version, the antifrost hot-water heating system also includes gas-liquid separator, the gas-liquid separator
Between the import of the compressor and cross valve, and it is respectively communicated with import and the cross valve in the compressor.The gas
The effect of liquid/gas separator is：The coolant gas liquid mixture of evaporator outlet enters gas-liquid separator and flows into bottom, and steam rises
Compressor is returned to top, liquid refrigerants gasifies gradually in the bottom of gas-liquid separator, is then return in compressor, so as to prevent
Liquid refrigerants enters compressor.
As a kind of preferred version, blower fan is also included, the blower fan is corresponding with the position of the vaporizer.Blower fan
Setting can increase the air capacity for flowing through evaporator surface, strengthen the effect of evaporation.
The beneficial effects of the utility model are：By separating one point in the pipeline from connection fluid reservoir and plate type heat exchanger
Bye-pass directly connects the vaporizer, then can realize that the coolant after plate type heat exchanger has
Device, plays the defrosting effect of vaporizer using the waste heat of coolant, so as to constantly carry out to vaporizer during refrigerant circulation
Defrosting, is not lost excessive heating capacity while shortening defrosting time, strengthening the defrosting effect of vaporizer again.
Description of the drawings
Fig. 1 is principle schematic of the present utility model.
Specific embodiment
Below with reference to accompanying drawing, the utility model will be further described, it should be noted that the present embodiment is with this skill
Premised on art scheme, detailed embodiment and specific operating process are given, but protection domain of the present utility model is not
It is limited to the present embodiment.
As shown in figure 1, a kind of antifrost hot-water heating system, including compressor 1, cross valve 2, plate type heat exchanger 3, fluid reservoir 5
With vaporizer 6, the inlet and outlet of the compressor 1, the plate type heat exchanger 3, vaporizer 6 are respectively communicated with the cross valve
2, the fluid reservoir 5 is communicated in the plate type heat exchanger 3, and is communicated in the vaporizer 6 by expansion valve 7；It is described board-like to change
Hot device 3 is respectively communicated with the inlet and outlet of a water pump 4；Connect on the connection fluid reservoir 5 with the pipeline of plate type heat exchanger 3
There is a branch line 8, the branch line 8 is directly communicates with the vaporizer 6；Toward the vaporizer 6 on the branch line 8
Direction be sequentially provided with check valve 9 and two-port valve 10.
Used as a kind of preferred version, the antifrost hot-water heating system also includes gas-liquid separator 11, the gas-liquid separation
Device 11 is between the import of the compressor 1 and cross valve 2, and is respectively communicated with import and the cross valve in the compressor 1
2.The effect of the gas-liquid separator is：The coolant gas liquid mixture of evaporator outlet enters gas-liquid separator and flows into bottom,
Steam rises to top and returns to compressor, and liquid refrigerants gasifies gradually in the bottom of gas-liquid separator, is then return in compressor,
So as to prevent liquid refrigerants from entering compressor.
As a kind of preferred version, blower fan 12 is also included, the blower fan 12 is corresponding with the position of the vaporizer 6.
The setting of blower fan can increase the air capacity for flowing through evaporator surface, strengthen the effect of evaporation.

Flow out from the outlet of water pump after being heated so as to water.The coolant after heat exchange is carried out and has gradually become low under the effect of the pressure
Warm liquid refrigerants flows out the plate type heat exchanger and leads to fluid reservoir.During towards fluid reservoir, coolant is from branched pipe all the way
Vaporizer is entered directly into by check valve and two-port valve in road, the waste heat of the road coolant plays defrosting to the frosting in vaporizer
Act on, and become gaseous coolant through vaporizer and come back to compressor.Except being directly entered vaporizer by branch line
The road coolant, another road coolant entered in fluid reservoir.Steaming is entered into through expansion valve into the liquid refrigerants in fluid reservoir
Send out the heat in device in absorption air and gasify, compressor is returned to again through cross valve.
When gas-liquid separator is provided with, it is introduced in gas-liquid separator from vaporizer gaseous coolant out, wherein gas
The coolant of state is introduced into compressor, and the coolant of liquid then sinks to the bottom of gas-liquid separator, comes back to compression after gradually gasifying
Machine.
For a person skilled in the art, technical scheme that can be according to more than and design, make various corresponding
Change and deform, and all these change and deformation should be construed as being included in this utility model scope of the claims it
It is interior.
