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

Embodiment Construction

[0028] Based on the current situation that traditional combined air conditioners use traditional heating methods in pursuit of dry bulb temperature and relative humidity, resulting in high energy consumption, the first aspect of the present invention provides a heat recovery device, which is used in the heat exchange with the air conditioner When combined with an air conditioner, it can use its own structure to realize heat or cold recovery, thereby reducing the energy consumption of the air conditioner.

[0029] Such as Figure 1-3 As shown, the heat recovery device of the present invention includes a subcooling coil 1 and a superheating coil 2, and the subcooling coil 1 and the superheating coil 2 are connected through a connecting pipe 3, and the superheating coil 2 The position is higher than the position of the subcooling coil 1, wherein the heat recovery device is filled with refrigerant, and the refrigerant is not filled with the heat recovery device when it is in a liq...

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...
