Absorption compression type super heat pump

Abstract

The invention discloses an absorption compression type super heat pump. A new process is adopted, heating or cooling requirements under large-range temperature change of the air are met in five running manners, separate heating or cooling can be realized, the special requirement for simultaneous heating and cooling can also be met, the heating temperature of the heat pump ranges from 50 DEG C to 150 DEG C, and the cooling temperature ranges from subzero 30 DEG C to 10 DEG C. According to the heat pump, an air compressor is used for adjusting the compression ratio of refrigerant vapor, so thatthe heating or cooling temperature is changed at the same air temperature. Compared with the prior art, the heat pump has the advantages that the heating and cooling working temperature range of the heat pump is enlarged remarkably, and the heat pump has the relatively high performance advantages.

Description

technical field [0001] The invention relates to the technical field of energy and environmental protection, in particular to a unit for producing hot water and cold water at different temperatures. Background technique [0002] Conventional industrial fields and civil fields have more cooling and heating needs. The conventional methods are boilers, heat pumps and refrigerators, etc., and various equipment can only meet the requirements of one heating or cooling parameter at the same time. At the same time, Different industrial users and civilian users have different temperature requirements for hot water and cold water, and there are also occasions where hot water and cold water with different temperatures and flows are required at the same time. Therefore, it is desirable to have a unit that simultaneously produces hot water and cold water at different temperatures , to solve the application problems existing in the current technology.

[0002] Conventional industrial fields and civil fields have more cooling and heating needs. The conventional methods are boilers, heat pumps and refrigerators, etc., and various equipment can only meet the requirements of one heating or cooling parameter at the same time. At the same time, Different industrial users and civilian users have different temperature requirements for hot water and cold water, and there are also occasions where hot water and cold water with different temperatures and flows are required at the same time. Therefore, it is desirable to have a unit that simultaneously produces hot water and cold water at different temperatures , to solve the application problems existing in the current technology

[0003] In addition, extracting heat from the air or releasing heat for heating or cooling has become one of the important technologies for energy saving and emission reduction. Air source heat pump technology is commonly used, but it is limited by the thermodynamic cycle, the physical properties of the working medium, and the temperature and pressure range of the compressor. The temperature difference between the condensation temperature and the evaporation temperature is generally less than 40°C when the air source heat pump is used for heating or cooling, which cannot meet the heating and cooling needs of various working conditions under a large temperature difference between the condensation temperature and the evaporation temperature. Against the above background, this invention proposes a multi-operation mode absorption compression super heat pump, which can realize heating or cooling demands under a wide range of temperature changes. Compared with the existing technology, this heat pump has the following advantages:
