Embodiment Construction

[0034] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following.

[0035] Such as figure 1 As shown, a ground source heat pump system includes a buried heat exchanger, a deep water heat exchanger, a compressor, a condenser, an evaporator, an expansion valve, a regulator, a circulating water pump, a decision module, and a The deep water heat exchanger refers to the heat exchanger placed in the ocean; the water in the deep water well is used as a liquid working medium, and the water in the deep water well is pumped to the buried heat exchanger by the circulating water pump, and the buried heat exchanger is connected to the compressed air. The compressor is connected to the condenser and the evaporator to complete heating and cooling respectively.

[0036] After the liquid working medium completes heating or cooling, it flows b...

Abstract

The invention relates to a ground source heat pump system. According to the system, a decision making module and a valve are introduced for control over a circulating path of a liquid-state working medium, thus, the problem of heat unbalance is converted into the problem of cold / heat utilization, heat is used for a fermentation system needing heat in summer, the liquid-state working medium is fedinto a system needing cold in winter, meanwhile, a deep water heat exchanger is introduced, the deep water heat exchanger mainly refers to a heat exchanger arranged in seawater, a huge system, namelythe sea is introduced to be used for small-scale heat exchange, sea heat balance (the sea heat radiation area is large, the specific heat capacity of water is large, and heating and cooling are slow)cannot be damaged, and the problem of sudden heat unbalance can be relieved to a certain degree.

Description

technical field [0001] The invention relates to the field of ground source heat pumps, in particular to a ground source heat pump system. Background technique [0002] The ground source heat pump system is generally composed of four parts: compressor, condenser, evaporator and expansion valve. By allowing the liquid working medium (refrigerant or refrigerant) to continuously complete: evaporation (absorb heat from the environment) → compression → condensation (release heat ) → throttling → re-evaporation thermodynamic cycle process, so as to transfer the heat in the environment to the water. Compressor (Compressor): It plays the role of compressing and transporting circulating working fluid from low temperature and low pressure to high temperature and high pressure. It is the heart of the heat pump (refrigeration) system; It is to evaporate the refrigerant liquid flowing in through the throttle valve to absorb the heat of the object to be cooled to achieve the purpose of re...
