Embodiment Construction

[0011] As shown in Fig. 1, the present invention is made up of solar heat collection system and multi-functional heat pump system, and solar heat collection system comprises solar energy all-glass vacuum tube heat collector 8 and thermal storage large water tank 10, the third electromagnetic valve 16 and high temperature circulation pump 20 , the solar all-glass vacuum tube heat collector 8 and the large heat storage water tank 10 can be placed on the roof or balcony according to the user's requirements and specific installation conditions. The water enters the solar all-glass vacuum tube heat collector 8 through the third solenoid valve 16, and the hot water heated in the solar all-glass vacuum tube heat collector 8 returns to the large heat storage water tank through the lower water inlet of the heat storage large water tank 10. 10. Cycle like this until the water temperature meets the design requirements. The multifunctional heat pump system mainly includes frequency conver...

Abstract

The multiple heat source multifunctional solar energy heat pump consists of one solar heat collecting system and one multifunctional heat pump system. The solar heat collecting system includes full glass tube solar heat collector, large heat accumulating water tank, solenoid valve and high temperature circulating pump; and the multifunctional heat pump system includes variable frequency compressor, outdoor water cooling source heat exchanger, outdoor air cooling source heat exchanger, indoor air cooling source heat exchanger, indoor coil pipe water heating tank, condensing coil pipe, electronic expansion valve, liquid storage and two electromagnetic triple valves. The solar heat collecting system and the multifunctional heat pump system are connected through the variable frequency high temperature circulating pump and solenoid valve. The present invention can utilize both solar energy and air source as the heat source of the heat pump, and has several functions and raised COP value of heat pump system.

Description

technical field [0001] The invention relates to a multi-heat source multifunctional solar heat pump. Background technique [0002] With the development of society and the improvement of people's living standards, energy consumption for heating, air conditioning and domestic hot water production accounts for an increasing proportion of the total energy. Therefore urban families are all equipped with heating and cooling dual-purpose air conditioners (technical terms are heat pumps) and water heaters (mainly electric water heaters, gas water heaters and solar water heaters). This will consume a large amount of conventional fossil energy (such as electricity, coal, oil, and natural gas). Air conditioning and domestic hot water production. According to the combination form of solar collector and heat pump evaporator, solar heat pump can be divided into direct expansion type and indirect expansion type.
