Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, simple and practical, is fit to the Teat pump boiler that the low northern area that indoor heating plant is arranged of environment temperature is used.
The present invention solves the technical scheme that above technical problem adopts: a kind of Teat pump boiler of suitable northern area comprises heat storage water tank and is provided with the refrigerant-cycle systems of compressor; Water is by heating heat-exchange device and condenser heating in the heat storage water tank; Described heating heat-exchange device can be located in the heat storage water tank, also can be located at outside the heat storage water tank to link to each other with the heating pipe road of condenser; The refrigerant-cycle systems of described compressor is provided with condenser, evaporimeter, vapour liquid separator, choke valve, environment temperature sensor and control device; Be provided with cooling-water temperature sensor in the described heat storage water tank.
The operation principle of Teat pump boiler of the present invention is: when environment temperature is higher than the temperature reference of setting, opens dynamic pressure and contract machine cooling system by the domestic hot-water in the condenser heating heat storage water tank; When environment temperature is lower than the temperature reference of setting, the closes compression machine cooling system, at this moment indoor heating has begun heating, by the domestic hot-water in the heating heat-exchange device heating heat storage water tank.
This structural design, saved the defrost system of Teat pump boiler, simplified the structure of Teat pump boiler, make Teat pump boiler both reduce cost, increased the operation stability of Teat pump boiler again, widened the scope of application of Teat pump boiler, be convenient to Teat pump boiler promoting the use of at north cold area.
