Sea-water heat-pump apparatus

Abstract

A heat pump of sea water consists of compressor , exchanger of cold / hot media water ( ECHMW ) , exchanger of sea water ( ESW ) , gas / liquid separator , refrigeration pipeline and computer control unit . It is prepared by setting four - way valve on pipeline between compressor and ECHMW as well as ESW, setting through valve on pipeline between ECHMW and ESW and having media passing through pipe set in ESW . The prepared heat pump can utilize energy resource of sea water adequately.

Description

technical field [0001] The invention relates to a heat pump device capable of cooling and heating, in particular to a heat pump device suitable for coastal areas that can utilize deep-sea seawater or underground seawater for heat exchange. Background technique [0002] The prior art has not yet provided a heat pump device that is particularly suitable for use in aquaculture and refrigeration processing industries in coastal areas, and that can make full use of the rich energy resources of deep seawater or underground seawater. Ordinary heat pump equipment in the prior art cannot be directly used in the above-mentioned places, because the structure of the heat exchanger currently adopted by the ordinary heat pump equipment is not reasonable enough. The above-mentioned heat exchangers mainly include plate heat exchangers and shell-and-tube heat exchangers. One of the plate heat exchangers is formed by pressing or brazing different types of plates, gaskets and other components....

AI Technical Summary

Problems solved by technology

Ordinary heat pump equipment in the prior art cannot be directly used in the above-mentioned places, because the structure of the heat exchanger currently adopted by ordinary heat pump equipment is not reasonable.

The above-mentioned heat exchangers mainly include plate heat exchangers and shell-and-tube heat exchangers. One of the plate heat exchangers is formed by pressing or brazing different types of plates, gaskets and other components. , After the plates are pressed or brazed, the contacts of adjacent plates are in contact with each other, so that a certain gap is maintained between the plates to form a fluid channel, and cold and hot fluid enter the fluid channel between the plates alternately for heat exchange. Although it has a high heat exchange rate, it has defects such as short medium running route, inconvenient cleaning, and complicated manufacturing process with corrosion-resistant materials; one of the shell-and-tube heat exchangers, the cold fluid inlet of this heat exchanger The inlet and outlet of the thermal fluid are often set on the same side of the casing, and the inlet and outlet of the thermal fluid are also set on the other side of the casing. This technical structure increases the difficulty of production on the one hand, and on the other hand, there are problems due to the change of the cross-sectional area of ​​the channel. The defect that the fluid cannot flow evenly and exchange heat and is inconvenient to clean

The technical defects of these two types of heat exchangers are inconvenient to clean, which makes it very unsuitable to use seawater as a heat exchange medium.
