Embodiment Construction

[0011] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] A seawater source heat pump air conditioning system applied to solar energy auxiliary heating, including a semi-open warm seawater circulation system and a heat pump system, the semi-open warm seawater circulation system includes a solar pond, a solar collector, a degasser, and a water pump; the heat pump system includes an evaporation Condenser, compressor, four-way reversing valve, condenser, throttle valve, water pump.

[0013] Working principle of the present invention is:

[0014] In winter, under heating conditions, valve 6 is closed, valve 5 is opened, seawater pump 7 pumps seawater with surface temperature, first flows through 2 solar pools for initial heating, and then flows through 3 solar collectors to continue heating, seawater temperature It is still a liquid when it is raised to the corresponding evaporation pressure of 60~80°C. The working flu...

Abstract

The invention discloses a seawater source heat pump air conditioning system for solar assisted heating. The seawater source heat pump air conditioning system includes a semi-open warm seawater circulation system and a heat pump system. The semi-open warm seawater circulation system comprises a seawater pump, a solar pond 2, a solar collector 3 and a degasser 4. The heat pump system includes a water pump 7, an evaporator 8, a compressor 9, a four-way valve 10, a condenser 11 and a throttle valve 12. The system can be used for cooling in summer and heating in winter and is adjusted by the use of the valve. The main features of the invention are that at the time of heat supply in the winter, the solar collector and the solar pond are used for heating the seawater twice, the temperature of low-temperature heat source (seawater) of the heat pump system is increased, therefore the efficiency of seawater source heat pump system is improved, and the energy is saved, and so forth.

Description

technical field [0001] The invention belongs to the technical field of heat pump air conditioners, and relates to a seawater source heat pump air conditioner system, in particular to a seawater source heat pump air conditioner system with solar energy auxiliary heating. Background technique [0002] As the name implies, the seawater source heat pump uses the huge amount of low-level energy stored in the ocean water on the surface of the earth. Through the heat pump unit, a small amount of electric energy is input to realize the transformation from low-level energy to high-level energy, and provide heating and cooling for building users. It is a renewable Energy-saving technology for cooling and heating. From a technical point of view, the heat pump equipment itself is relatively mature. However, when applied to seawater source heat pump systems, there are some problems, such as seawater corrosion, marine organism adhesion, scaling, and seawater antifreeze; The heat pump sy...
