Direct-contact seawater source heat pump

Abstract

A direct-contact seawater source heat pump mainly comprises the following parts: a seawater-refrigerant heat exchanger, a circulating water-refrigerant heat exchanger, a four-way valve, a compressor, an expansion valve, a plurality of valves and a plurality of pipelines; a lower refrigerant pipe is led out of the seawater-refrigerant heat exchanger and is connected with one end of the expansion valve; an upper refrigerant pipe is led out of the seawater-refrigerant heat exchanger to the four-way valve; the compressor is in parallel connection with the four-way valve; the other end of the four-way valve is connected with the upper part of a cylinder body of the circulating water-refrigerant heat exchanger through the upper refrigerant pipe; and the lower refrigerant pipe arranged at the bottom of the circulating water-refrigerant heat exchanger is connected to one end of the expansion valve. The direct-connected seawater source heat pump is characterized in that the seawater-refrigerant heat exchanger is a direct-contact heat exchanger.

Description

technical field [0001] The invention relates to heat pump technology, in particular to a direct seawater source heat pump. Background technique [0002] Using seawater as a cold and heat source, heating and air-conditioning buildings through seawater source heat pumps can directly reduce the consumption of other energy shortages, and at the same time achieve the purpose of waste utilization. important measures of the environment. [0003] The seawater source heat pump realizes the recycling of waste heat and turns waste into treasure. It is a new type of renewable and clean energy utilization technology, which meets the requirements of sustainable development and building a resource-saving society. The combination of water source heat pump system technology and urban seawater has far-reaching significance in expanding the scope of urban seawater utilization and expanding the benefits of urban seawater treatment. [0004] The seawater source heat pump relies on the physical...

Problems solved by technology

[0017] 2. The direct seawater source heat pump unit uses seawater as the heat source, which is easy to corrode, pollute and block, which will reduce the efficiency of the seawater source heat pump and even fail to work

[0019] The working conditions of direct seawater source heat pumps are very different from ordinary heat exchangers. The design method and experience of ordinary heat exchangers cannot be simply used for direct seawater source heat pumps, especially seawater-refrigerant heat exchangers.

[0020] Although the design method and manufacturing process of ordinary heat exchangers are very mature, the scientific design method of direct seawater source heat pump has not yet been well solved.
