Air conditioner with ventilation function

Abstract

The invention discloses an air conditioner with air-changing function, which comprises the following parts: air-out channel for discharging the indoor air outdoors, air-changing unit of sensible heat converter for heat conversion in the air-supply and air-out intercourse, refrigeration circulation air conditioner unit with evaporation heat converter on the air-supply channel, wherein the air conditioner unit contains inner circulation channel for inflowing the indoor air of evaporation heat converter; the air-changing unit contains simple air-changing channel to discharge the air outdoors directly without flowing through the sensible heat converter.

Description

technical field [0001] The present invention relates to an air conditioner, and more specifically relates to an air conditioner with ventilation function for replacing indoor polluted air with outdoor fresh air. Background technique [0002] Commonly used air conditioners are used to circulate the air, and at the same time, they are linked with the refrigeration cycle to cool the indoor air and reduce the indoor temperature. The structure can be roughly divided into indoor units and outdoor units. The above-mentioned indoor unit and outdoor unit are called an integrated type air conditioner, and those that are separately installed are called a split type air conditioner. [0003] The representative ones of the integrated air conditioners are window-type air conditioners, and the representative ones of the split-type air conditioners are wall-mounted and cabinet-type air conditioners. [0004] The refrigerating cycle system of this air conditioner is based on: a compressor t...

Problems solved by technology

[0011] However, the ventilation device of the above-mentioned air conditioner directly discharges the indoor air to the outside, so it cannot fundamentally solve the problem of low refrigeration efficiency caused by ventilation.

That is, not only the indoor cold air is directly discharged to the outside, but also the outdoor hot air flows directly into the room, so the indoor temperature rises, resulting in low cooling efficiency

[0012] Moreover, the exhausted indoor air is fully cooled. If this energy is used, the supplied outdoor air can be fully cooled. However, the previous ventilation devices did not take this into account, but simply involved the exhausting of indoor air and the outdoor air. air supply
