Although meter the antifreeze of heat exchanging device has certain effect, the leak point of unit refrigerant is increased, especially to the skill of installer
Art requirement is very high, and new clothes unit often occurs in market, and because leakage causes cold medium shortage, protectiveness is shut down.
Utility model content
To solve the above problems, the utility model provides a kind of simple structure, recirculated water automatic-discharging that can be antifreeze is adopted
Heating system.
The utility model solves the technical scheme that its technical problem used：
A kind of heating system of recirculated water automatic-discharging, including heat exchanger, the confession that is connected by pipeline with heat exchanger respectively
Hot junction and heating terminal, are additionally provided with two-port valve and water circulating pump on the pipeline that heat exchanger is connected with heating terminal, two-port valve connects
Drainpipe is connected to, the power end of two-port valve is connected with the power output end of heating terminal.
Used as the further improvement of above-mentioned technical proposal, heat supply end is provided with the refrigerant inlet pipe and refrigerant being connected with heat exchanger
Outlet pipe, heating terminal is provided with the water inlet pipe and outlet pipe being connected with heat exchanger, and two-port valve and water circulating pump are arranged on water inlet pipe
On.
As the further improvement of above-mentioned technical proposal, heat supply end pipeline fluid flow direction and heating end in heat exchanger
End pipe road fluid flow direction is opposite.
Used as the further improvement of above-mentioned technical proposal, two-port valve is electromagnetism two-port valve.
The beneficial effects of the utility model：The heating system of this recirculated water automatic-discharging is by two-port valve and water circulating pump
Set, because of the power output end connection of the power end and heating terminal of two-port valve, therefore when power is off, the valve opening of two-port valve,
Recirculated water in pipeline is discharged along drainpipe, so avoid freeze after damage the generation of heating terminal pipeline, the recirculated water
The heating system simple structure of automatic-discharging, can play antifreeze effect.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the heating system of recirculated water automatic-discharging.
Specific embodiment
Reference picture 1, the utility model is a kind of heating system of recirculated water automatic-discharging, including heat exchanger 1, respectively with change
