Solar heat pump and water heating integrated machine

Abstract

The invention relates to an integrative machine of solar energy heat pump and hot water, comprising a water tank body, a heat collecting pipe and the pipe supporting box and the bracket of the heat collecting pipe. A condenser is arranged at the middle lower part in the water tank body; a compressor outside the water tank body is connected with a four-way valve; the high temperature working medium outlet on the four-way valve is connected with one end of the condenser, and the other end of the condenser is connected with evaporator through a current regulator which is connected with a low temperature working medium inlet on the four-way valve; the return working medium port of the four-way valve is connected with a liquid storage tank which is connected into a whole with the compressor; a ventilation hole is arranged on a shell which is corresponding to the evaporator; the shell is connected with the shell of the water tank body; the ventilation hole is communicated with the end cover of the air outlet of a fan; the end cover of the air outlet of the fan is internally provided with a fan. As the integrative machine of solar energy heat pump and hot water adopts the structure, the appearance is simple and beautiful; in sunny days, hot water can be generated by solar energy; in cloudy and rainy days, energy-saving auxiliary heating is realized by the heat pump; the efficiency is high, the energy is saved, the installation has little land occupying, and the integrative machine of solar energy heat pump and hot water is beneficial for batch dense-typed installation and application.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a solar heat pump and hot water integrated machine in which solar energy and a heat pump are integrated. Background technique [0002] With the increasing shortage of energy, the use of new energy and new technologies has become the development direction. The combination of solar energy and heat pumps will be a very energy-saving hot water generating equipment. Currently, solar energy and heat pumps are installed separately and connected by pipes. , such as Chinese Patent No. ZL 200520056738.6 discloses "a solar water heater with an auxiliary heating device". Based on the existing solar water heater, a heat exchanger is set in its water storage tank, and a heat pump installed next to it The host is connected to generate hot water, and the solar water heater is used for auxiliary heating in rainy days. It failed to achieve integration, and the heat exchanger in the solar water heater tank ...

AI Technical Summary

Problems solved by technology

It failed to achieve integration, and the heat exchanger in the solar water heater tank and the working fluid inlet and outlet of the heat pump must be connected with each other with long metal pipes. Occupies a large space, which is not conducive to intensive installation and use
