Abstract

The invention relates to an air conditioning system indoor heat exchanging structure. The air conditioning system indoor heat exchanging structure comprises a heat radiating type indoor heat exchanger and a second indoor heat exchanger, and only the second indoor heat exchanger is internally provided with an indoor fan. The heat radiating type indoor heat exchanger and the second indoor heat exchanger are connected in parallel or in series. According to the air conditioning system, the plate type heat exchanger is additionally arranged in an indoor unit in a mode of parallel connection or series connection, the temperature is held through the plate type heat exchanger after being up to a set value, and the indoor fan is closed, so that the purposes of energy conservation and noise reduction are achieved. The comfortability of the air conditioning system is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to an indoor heat exchange structure of an air conditioning system, an air conditioning system and a control method thereof. Background technique [0002] The initial room load of the air-conditioned room is large, and the air conditioner operates at the highest speed and full load. With the extension of the operating time, the room load demand decreases, and the air conditioner operates at a low speed. Frequency generators meet room load changes through intermittent start and stop. Both of these two variable load control methods require the fan to run for a long time, which consumes a lot of power, and the noise is high and the comfort is not good. Contents of the invention [0003] In view of this, the object of the present invention is to provide an indoor heat exchange structure of an air-conditioning system, an air-conditioning system and a control method ...
