A heat pump hot-water unit for recovering food grade residual heat recovery

Abstract

The invention discloses a heat pump hot-water unit for recovering food grade residual heat which is of lower-level heat source and which is produced in a liquid-cooling and storage equipment used in the production process of the diary industry, the beverage industry, the wine industry and the pharmaceutical industry, etc. The heat pump hot-water assembly comprises a refrigerated tank, a circulating pump of the refrigerated tank, an evaporator, a high-temperature water case, a circulating pump of the high-temperature water case, a low-temperature water case, a circulating pump of the low-temperature case, a vapor-liquid separator, a compressor, a filter, a expansion valve, a high-temperature condenser and a low-temperature condenser. The advantages of the invention can be demonstrated in the following aspects: simple in structure; all components being able to be dismantled and washed; no need for energy; energy-saving and environmental-protective; capable of producing certain amount of high-temperature water and low-temperature water without additional input besides performs the function of freshness preservation through lowering temperature of refrigerated liquid.

Description

Technical field: [0001] The invention relates to a food-grade waste heat recovery heat pump hot water unit for recovering and utilizing low-level heat sources generated by liquid cooling storage equipment in the production process of dairy production, beverage, wine making and pharmaceutical industries. Background technique: [0002] At present, in the production process of dairy production, beverage, wine making and pharmaceutical industries, liquids such as fresh milk, beverages, injection medicines, etc. need to be cooled and packaged or stored. Most of the equipment used is a single refrigeration equipment and cooling tower. A large number of low-level heat sources generated during the cooling process are discharged in vain. Moreover, the equipment used is bulky and expensive, and the refrigerant Freon used in the refrigeration equipment does not meet environmental protection requirements. Hot water for production is necessary in these industries, and most of the hot w...

Problems solved by technology

Moreover, the equipment used is bulky and expensive, and the refrigerant Freon used in refrigeration equipment does not meet environmental protection requirements.

In these industries, hot water is necessary for production. Most of the hot water preparation methods used are coal-fired and oil-fired boilers, which are costly and not environmentally friendly.
