The invention relates to a fresh air temperature and humidity control system which comprises an outdoor control part and an indoor control part which communicate with each other. The outdoor control part comprises a compressor, a four-way valve and a first heat exchanger; and the indoor control part comprises a second heat exchanger, a third heat exchanger and a switching valve. A fresh air conditioner comprises the fresh air temperature and humidity control system. A fresh air dehumidification air temperature control method is suitable for the fresh air temperature and humidity control system or the fresh air conditioner; the control system monitors the outlet air temperature tc and the return air temperature t through a temperature sensor; and the control method comprises a constant-temperature dehumidification method and an isothermal dehumidification method. According to the control system and the fresh air conditioner provided by the invention, the functions are complete, the structural integration degree is high, the energy efficiency is high, refrigeration, heating and dehumidification of fresh air can be achieved, the dehumidification effect is good, the air outlet temperature cannot be too high or too low, the somatosensory comfort degree is good, the temperature of dehumidified outlet air can be further adjusted through the control method, and the somatosensory comfort degree is improved.
Description
technical field [0001] The invention relates to the technical field of fresh air equipment, in particular to a fresh air temperature and humidity control system, a fresh air air conditioner, and a fresh air dehumidification air temperature control method. Background technique [0002] In the development process of the fresh air system, the all-heating fresh air fan is a relatively popular model. This kind of fresh air fan has a simple structure, which is to introduce fresh air and discharge indoor return air through an exhaust fan and a supply fan. Heat exchange is carried out in the total heat exchange core. For example, the patent document with application number CN201820051549.7 discloses a total heat exchange fresh air blower, its structure includes a full heat exchange fresh air blower body, a total heat exchanger, an indoor air inlet, an outdoor air inlet, an indoor air outlet, and an outdoor air outlet , a centrifugal fan, a purification device and a heating device, ...
