Fresh air conditioner and control method thereof

Abstract

The invention provides a fresh air conditioner and a control method thereof. The fresh air conditioner comprises a shell, a heat exchange core and a heat pipe assembly, a fresh air channel and an airreturn channel are constructed in the shell, fresh air flow in the fresh air channel and air return flow in the air return channel conduct heat exchange at the heat exchange core, the heat exchange core divides the fresh air channel into a fresh air inlet section and a fresh air outlet section, the heat pipe assembly comprises a first heat pipe section and a second heat pipe section, the first heat pipe section is located in the fresh air inlet section, the second heat pipe section is located in the fresh air outlet section, and a refrigerant in the heat pipe assembly can selectively flow between the first heat pipe section and the second heat pipe section. According to the fresh air conditioner, the first heat pipe section and the second heat pipe section of the heat pipe assembly are arranged in the fresh air inlet section and the fresh air outlet section of the fresh air channel correspondingly, the heat exchange core can be effectively prevented from being frozen in the low-temperature environment, power consumption is small, efficiency is high, energy is saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a fresh air conditioner and a control method thereof. Background technique [0002] In order to save energy and improve the comfort of fresh air supply, a heat exchange core is often introduced into the two-way flow fresh air unit to recover energy from the exhaust air. However, when the heat exchange core is used in an ultra-low temperature environment, there will be a problem of freezing, which makes the heat exchange core unable to be used normally. At present, the main solution to this problem is to add an electric auxiliary device in front of the heat exchange core and at the entrance of the fresh air. The temperature of the fresh air solves the problem of core freezing. However, the electric auxiliary heating device is a resistive component, which consumes a lot of power and has low efficiency, which is not conducive to energy saving. Contents of the...

Problems solved by technology

However, when this heat exchange core is used in an ultra-low temperature environment, there will be freezing problems, which will cause the heat exchange core to fail to work normally.

At present, the main solution to this problem is to add an electric auxiliary device in front of the heat exchange core and at the entrance of the fresh air. Fresh air temperature solves the problem of core icing. However, the electric auxiliary heating device is a resistive component, which consumes a lot of power and has low efficiency, which is not conducive to energy saving.
