Precooler for ventilation of air conditioner

Abstract

This invention discloses a kind of precooler for air conditioner ventilation. It includes: catch basin, which collects the drippy condensation water form at the surface of evaporator due to absorbing surrounding air heat during refrigerants circulating; ventilating duct, which is arranged in the catch basin. The air refrigerated by condensation water in the catch basin is circulated in the ventilating duct and is used for ventilating. There is entrance for injecting condensation water at one side of the top of catch basin. There is also exit for discharging condensation water at the other side of the top of the catch basin and is it lower than the entrance. The ventilating duct and condensation water flowing direction are vertically arranged. The air refrigerated by condensation water before providing in doors. It minimizes the raising of indoor temperature and air conditioner load. This invention further increases heat exchange efficiency and can realize miniaturization of products.

Description

technical field [0001] The invention relates to an air conditioner. In particular, it relates to a pre-cooling for ventilation of an air conditioner that reduces the humidity and temperature of the air sucked in from the outside for the purpose of ventilation in the room, and can effectively prevent the increase in the load caused by the increase in the room temperature and humidity. device. Background technique [0002] An air conditioner is a device that supplies inhaled air to a building or a room, and treats the indoor air to maintain a suitable condition. It can be roughly divided into split type air conditioners and integrated air conditioners. [0003] Although the split type and the integrated type are roughly the same in terms of function, the split type is to install the cooling device indoors, and install the heat dissipation and compression device outdoors, and connect the two separate devices through refrigerant pipes. The integrated type is to integrate the f...

Problems solved by technology

[0014] However, since the ventilating precooler of the air conditioner of the prior art exchanges heat between the indoor air A of the body and the ventilating air B, the reduction of the heat transfer rate leads to a reduction of the heat exchange efficiency. The heat is exchanged, and it is impossible to control the humidity of the ventilation air B

[0015] As a result, the moisture contained in the ventilation air B will cause discomfort to the user during ventilation, and the residual heat load caused by this moisture should be borne by the air conditioner. Power is also a consumption

[0016] In addition, the same as above, the reduction of cooling capacity and the increase of power consumption will reduce the efficiency of the air conditioner, followed by the increase of the capacity of the air conditioner, so the product volume will become larger, and the price will inevitably rise
