Air conditioning device, multi-linkage indoor unit system and control method thereof

Abstract

The invention provides a multi-linkage indoor unit system. The multi-linkage indoor unit system comprises a connecting pipe set, two heat exchanger sets, a throttling element, a valve assembly, a compressor and a throttling pipeline, wherein the connecting pipe set comprises a liquid pipe, an air pipe, a first branch pipe, a second branch pipe and a connecting branch pipe; the valve assembly comprises a first valve, a second valve and a third valve; the compressor and the second valve are arranged in parallel; one end of the throttling pipeline communicates with the first branch pipe which is between the liquid pipe and the corresponding heat exchanger set; the other end of the throttling pipeline communicates with the second branch pipe which is between the third valve and the corresponding heat exchanger set. According to the multi-linkage indoor unit system, the throttling element, the first valve, the second valve and the third valve are closed, and the compressor runs during dehumidifying, and the two heat exchanger sets can be correspondingly used for performing condensing heat exchanging and evaporating heat absorbing, so that the efficient dehumidifying can be achieved on the premise that the environmental temperature is influenced a little, and as a result, the electricity consumption is decreased, and the dehumidifying effect is improved. The invention also provides an air conditioning device and a control method of the multi-linkage indoor unit system.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to an air-conditioning equipment, a multi-connected indoor unit system and a control method thereof. Background technique [0002] In the southern part of my country, the house is very humid in spring, and the clothes are prone to mildew. Especially for the cloakroom and other rooms where clothes are stored, it is very necessary to turn on the dehumidification function of the air conditioner. However, for the current household multi-connection units, only running an air conditioner in the cloakroom to dehumidify is a waste of electricity, and the outdoor unit runs for a long time with low frequency noise, which also has a negative impact on the reliability of the compressor. More importantly, , Dehumidification only by refrigeration, the dehumidification effect is not ideal, affecting the use. Contents of the invention [0003] Based on this, it is necessary to...
