Abstract
The utility model relates to a heat-pump water heater. The heat-pump water heater comprises a compressor, a four-way valve, a condenser, an expansion valve, an evaporator and a liquid receiver, wherein a refrigerant loop is arranged among the compressor, the four-way valve, the condenser, the expansion valve, the evaporator and the liquid receiver; a medium-temperature condenser is arranged in the refrigerant loop and connected in series with the condenser; and a bypass pipe is connected between the inlet port and the outlet port of the medium-temperature condenser and provided with a solenoid valve. The heat-pump water heater has reasonable and simple structural design and high-temperature waste heat of a refrigerant is absorbed by arranging the condenser in the refrigerant loop. More medium-temperature water can be produced and better overheat protection can be performed on the compressor.
Description
Technical field
The utility model relates to a kind of Teat pump boiler.
Background technology
Existing heat pump water-heating machine preparing high-temp hot water efficient is low, when the cold-producing medium of high temperature enters evaporimeter, evaporability is obviously reduced, and causes overheat of compressor.
Summary of the invention
Therefore, the purpose of this utility model be to provide a kind of can to compressor carry out overtemperature protection, can produce warm water's Teat pump boiler again.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of Teat pump boiler, comprise compressor, cross valve, condenser, expansion valve, evaporimeter and liquid reservoir, constitute a refrigerant loop between them, warm condenser in also being provided with in the described refrigerant loop, in warm condenser and condenser be connected in series, in be communicated with bypass pipe between the turnover port of warm condenser, bypass pipe is provided with magnetic valve.
The utility model reasonable in design is simple, by setting up a condenser again in refrigerating circuit, absorption refrigeration agent high-temperature residual heat.Promptly can make more middle warm water, can better carry out overtemperature protection to compressor again.
Description of drawings
Principle schematic when accompanying drawing heats water for embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In conjunction with the accompanying drawings, a kind of Teat pump boiler, comprise compressor 1, cross valve 2, high temperature condenser 3, middle temperature condenser 4, expansion valve 5, evaporimeter 6 and liquid reservoir 7, constitute a refrigerant loop between them, wherein high temperature condenser 3 is connected in series successively with middle temperature condenser 4, in be communicated with bypass pipe 8 between the turnover port of warm condenser 4, bypass pipe 8 is provided with magnetic valve 9.When Teat pump boiler had just started use, magnetic valve was opened, and middle temperature condenser is by bypass, and when the cold-producing medium that comes out from the high temperature condenser reached uniform temperature, magnetic valve just cut out, and middle temperature condenser begins to make warm water.During defrosting, magnetic valve is configured to open mode.
Claims (1)
1. Teat pump boiler, comprise compressor, cross valve, condenser, expansion valve, evaporimeter and liquid reservoir, constitute a refrigerant loop between them, it is characterized in that: warm condenser in also being provided with in the described refrigerant loop, in warm condenser and condenser be connected in series, in be communicated with bypass pipe between the turnover port of warm condenser, bypass pipe is provided with magnetic valve.
