A heat recovery device and an air conditioner having the same

Abstract

A heat recovery device, comprising a supercooling coil pipe (1) and an overheating coil pipe (2), the supercooling coil pipe (1) and the overheating coil pipe (2) being connected by means of a connecting pipe (3), the position of the overheating coil pipe (2) being higher than the position of the supercooling coil pipe (1), and the heat recovery device being filled with refrigerant. When the heat recovery device is combined with a heat exchanger (4) of an air conditioning apparatus, the heat of high temperature fresh air converts liquid refrigerant in the supercooling coil pipe (1) into gaseous refrigerant, and the gaseous refrigerant flows via the connecting pipe (3) into the overheating coil pipe (2) that is positioned relatively higher; low temperature fresh air exiting the heat exchanger (4) can re-convert the gaseous refrigerant in the overheating coil pipe (2) into liquid refrigerant, and the liquid refrigerant flows under the action of gravity via the connecting pipe (3) into the supercooling coil pipe (1) that is positioned relatively lower; this manner of circulation can automatically implement recovery of heat or cold.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat recovery device and an air conditioning device having the same. Background technique [0002] When people use air conditioners to adjust the indoor environment, they not only require to achieve a comfortable temperature, but also require a healthy and suitable humidity. It is generally believed that an environment with a relative humidity between 50% and 60% is an environment that is conducive to health and feels comfortable, and the relative humidity that is too high or too low will affect the comfort. In order to enable the air conditioner to achieve this goal, in order to meet the dry bulb temperature and relative humidity set in the room, the traditional combined air conditioner often uses traditional heating methods (steam or electric heating) to increase the relative humidity of the air sent into the room. This often results in unnecessary waste of resource...

AI Technical Summary

Problems solved by technology

In order to enable the air conditioner to achieve this goal, the current traditional combined air conditioner often uses traditional heating methods (steam or electric heating) to increase the relative humidity of the air sent into the room in order to meet the dry bulb temperature and relative humidity set in the room. This often results in unnecessary waste of resources

[0003] In the prior art, there is no air conditioner that can use its own structure to recover excess heat to preheat the air and increase the relative humidity
