Embodiment

[0026] Such as figure 1 As shown, the tower-type solar heat pump hot water system includes a circulating heat exchange system composed of an evaporator 1, a compressor 4, an expansion valve 5 and a condenser 6; It is connected with the evaporator 1, the compressor 4 and the expansion valve 5 which are arranged on the top of the water tank 8; The heat system and the water tank 8 are covered in the tower.

[0027] The working process of the circulating heat exchange system is: the compressor 4 compresses the returning low-pressure refrigerant to become a high-temperature and high-pressure refrigerant gas, and the high-temperature and high-pressure refrigerant gas flows through the condenser 6 in the water tank, and the heat is released to the water tank through the condenser 6 The water is heated inside, and the cooled refrigerant becomes liquid under the continuous action of the pressure, and enters the evaporator 1 after passing through the expansion valve 5. Since the pressu...

Abstract

The invention discloses a tower type solar energy heat pump hot water system comprising a circulating heat exchanging system composed of an evaporator, a compressor, an expansion valve and condenser. The condenser is arranged at the inner part of a water tank and is connected with the evaporator, the compressor and the expansion valve by a pipeline; the evaporator, the compressor and the expansion valve are arranged on the top part of the water tank; the evaporator is connected with heat collection plates; and the heat collection plates are unfolded at the periphery of the evaporator to form a tower type structure to cover the circulating heat exchanging system and the water tank in a tower. In the tower type solar energy heat pump hot water system, the tower type structure formed by the solar energy heat collection plates and the heat pump evaporator through combination is adopted, and the air in the tower is heated through radiation to the inside of the tower by the heat collection plates by absorbing solar energy and heat convection, therefore, the water tank and the compressor can be insulated, external heat dissipation of the water tank can be reduced, overcooling of the compressor can be prevented, radiation loss of the system to the environment is effectively reduced, and the heat efficiency is improved.

Description

technical field [0001] The invention relates to a solar heat pump water heating system, in particular to a tower type solar heat pump water heating system. Background technique [0002] The combination of solar energy and heat pump technology is called a solar heat pump system. A solar heat pump combines a solar collector with a heat pump evaporator, and directly utilizes the low-grade heat source of the surrounding environment (sun radiant energy is the main source, and air heat source is the supplementary), so that The evaporation process of refrigerant and the heat collection process of solar energy are carried out in the same device. According to the combination form of solar collector and heat pump evaporator, it can be divided into direct-expansion solarar assisted heat pump (DX-SAHP) and non-direct expansion. In the direct expansion system, the solar collector and the heat pump evaporator are combined into one, that is, the refrigerant directly absorbs solar radiatio...
