Separate combination type air heat regenerator

Abstract

The invention relates to a separate combination type air heat regenerator, solving the recycling problem of air heat (cryogenic) energy in an air conditioner system. The invention comprises a hot sideheat exchanger, a cold side heat exchanger, a hot side fan and a cold side fan; the heat exchangers comprise more than one row of heat exchanging pipes, each row comprises more than ten heat exchanging pipes; the upper extending-outwards end of each heat exchanging pipe on each row is respectively communicated with an air converging pipe through a connecting pipe, and one end of four air converging pipes is an air inlet end or an air outlet end; the lower extending-outwards end of each heat exchanging pipe on each row is respectively communicated with a liquid converging pipe through a connecting pipe, and one end of four liquid converging pipes is a liquid outlet end or a liquid inlet end. The invention is a high effective air heat exchanger, as long as the temperature difference of coldair flow and hot air flow exceeds 3 DEG C the energy can be recycled, and with the increase of the temperature difference of cold air flow and hot air flow the energy saving effect grows more obvious. The invention can be widely applied in conditions such as air cooling, air heating, air backheating and the like in refrigeration air conditioner laboratories.

Description

technical field [0001] The invention relates to an air heat exchanger, in particular to a separated and combined air heat recovery device. Background technique [0002] There are a large number of cooling and heating processes in a large number of industrial production systems, test and detection systems, etc., especially the two test environments of various refrigeration and air-conditioning laboratories need to cool and heat the air in the two environments at the same time. These cooling and heating processes are not comprehensively designed and utilized in many occasions, resulting in a large amount of waste of high-quality energy; on the other hand, the cooling process does not make full use of environmental conditions for cooling, which also increases the consumption of a large amount of high-quality energy. The traditional environmental treatment methods used in these air-conditioning systems consume a lot of energy. One of the characteristics of energy consumption is ...

[0002] There are a large number of cooling and heating processes in a large number of industrial production systems, test and detection systems, etc., especially the two test environments of various refrigeration and air-conditioning laboratories need to cool and heat the air in the two environments at the same time. These cooling and heating processes are not comprehensively designed and utilized in many occasions, resulting in a large amount of waste of high-quality energy; on the other hand, the cooling process does not make full use of environmental conditions for cooling, which also increases the consumption of a large amount of high-quality energy

The traditional environmental treatment methods used in these air-conditioning systems consume a lot of energy. One of the characteristics of energy consumption is that the system has heat supply (cold) and heat exhaust (cold) processes at the same time. If the heat to be discharged ( The cold) is transferred to the place where heat (cold) is needed, that is, heat energy recovery can effectively use energy
