Abstract

The invention provides a constant-humidity and constant-oxygen gravity all heat recovery anti-freezing fresh air unit and an air conditioner, and belongs to the field of air conditioners. The constant-humidity and constant-oxygen gravity all heat recovery anti-freezing fresh air unit comprises a heat recovery module, a humidity adjusting module, a first reheat recovery surface cooler, a second reheat recovery surface cooler, a main surface cooler, a filter module, a fan and an external cold and hot source; the first reheat recovery surface cooler, the humidity adjusting module, the main surface cooler, the second reheat recovery surface cooler, the fan and the filter module are arranged on one side of the heat recovery module in sequence; the main surface cooler is connected with the external cold and hot source; and an output end of the fan is arranged towards the filter module. Outdoor low-temperature air of a split anti-freezing gravity all heat recovery device firstly passes through a saline solution heat recovery device; fresh air recovers heat of indoor exhausted air of 20 DEG C; and outdoor fresh air is preheated and humidified, enters the saline solution for further heatingand humidification, and enters the heat supply surface cooler for heating to send into rooms, so that the air conditioner still can be started when outdoor temperature is lower than 0 DEG C.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a constant humidity and constant oxygen type gravity full heat recovery antifreeze fresh air unit and an air conditioner. Background technique [0002] In the digital intelligent fresh air system, the heat recovery only adopts the sensible heat recovery method, and the heat recovery of the runner, plate-fin type, etc. can also be used. The heat pump heat recovery solution humidity control unit uses the heat pump to cool, dehumidify, heat, and humidify the fresh air. Since the efficiency of the heat pump is basically around COP3.0, the digital intelligent fresh air system only uses ethylene glycol solution for sensible heat recovery. Rotary heat recovery or plate-type heat recovery can also be used. The rotary heat recovery has the problem of cross-contamination of fresh air and return air. The sensible heat recovery of ethylene glycol solution is inefficient and the system is comp...
