Air-conditioner

Abstract

The invention provides an air-conditioner. The air-conditioner comprises a shell, a draught fan, an indoor heat exchanger and an outdoor heat exchanger, wherein the draught fan, the indoor heat exchanger and the outdoor heat exchanger are arranged inside the shell. The draught fan is provided with an air inlet taking in air from the interior, an outdoor air outlet sending the air outdoors and an indoor air outlet sending the air indoors. The outdoor heat exchanger and the outdoor air outlet are arranged correspondingly. The indoor heat exchanger and the air inlet or the indoor air outlet are also arranged correspondingly. According to the air-conditioner, the draught fan is provided with the outdoor air outlet, the indoor air outlet and the air inlet taking in the air from the interior, and the outdoor heat exchanger is subjected to heat exchange with airflow entering from the air inlet in the working process; and due to the fact that the indoor working condition is generally superior to the outdoor working condition, the problems that the air-conditioner cannot be started and operating efficiency is low due to severe outdoor working conditions are prevented, and the operating efficiency of the air-conditioner is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner. Background technique [0002] In the prior art, both the evaporator and the condenser of the air conditioner have independent heat dissipation systems, which generally require an evaporating fan duct system and a condensing fan duct system, and the two systems are independent of each other, which often makes the outdoor unit If the size is too large, it may cause the installation position to be too small to be installed. In addition, the general operating conditions of outdoor units are relatively harsh. If encountering high temperature or severe cold weather, the operating efficiency of the unit is very low, resulting in the cooling or heating capacity of the outdoor unit being greatly weakened, or even shutting down; moreover, the two sets of heat dissipation The system increases the manufacturing cost of the air conditioner.

In addition, the general operating conditions of outdoor units are relatively harsh.
