Abstract

The invention discloses a multi-functional multi-connected air-conditioning system which comprises a cooling system, a heating system and a dehumidifying system, wherein the cooling system is designedto be a circulating loop constituted by a compressor, an oil separator, a four-way valve, an air-cooled heat exchanger, a first flow dividing assembly, a throttling assembly, an indoor unit and the compressor which are connected in sequence; the heating system is designed to be a circulating loop constituted by the compressor, the oil separator, the four-way valve, an indoor underfloor heating coil pipe, a throttling mechanism, the air-cooled heat exchanger and the four-way valve which are connected in sequence; and the dehumidifying system is designed to be a circulating hoop constituted bythe compressor, the oil separator, the four-way valve, the indoor underfloor coil pipe, a liquid collecting assembly, the throttling assembly, the indoor unit, an air-liquid separator and the compressor which are connected in sequence. The multi-functional multi-connected air-conditioning system integrates the cooling function of a multi-connected air conditioner and the advantage of a water-basedunderfloor heating air conditioner; the direct heat exchange operation is adopted, the use of a water pump is eliminated, and the maintenance is reduced; by use of the reheating function designed forthe dehumidifying operation, a floor is heated; through the indoor unit for cooling, the cooling operation and the humidifying operation are performed simultaneously; the strong and rapid dehumidifying effect is achieved; and one multi-functional multi-connected air-conditioning system serves several purposes.

Description

technical field [0001] The invention belongs to the field of refrigeration systems, in particular to a multi-connected air-conditioning system for refrigeration, heating and dehumidification. Background technique [0002] The cooling mode of the multi-connected air-conditioning system is basically the same, but the heating is different. The multi-connected cooling and heating use the same indoor unit. For common multi-split units, the temperature in the area close to the air outlet of the indoor unit is high during heating, and the temperature in the area far away from the air outlet is relatively low. The uniformity of the temperature field in the entire space is not good, and the comfort is not good. The water coil heating solves this problem, but it needs to increase the circulating water pump, the water pump needs additional power consumption, the water pipe needs antifreeze treatment, troublesome debugging, secondary heat exchange, and low energy efficiency. The dehumi...

Problems solved by technology

When the common multi-split unit is heating, the temperature in the area close to the air outlet of the indoor unit is high, and the temperature in the area far away from the air outlet is relatively low. The uniformity of the temperature field in the entire space is not good, and the comfort is not good. The water coil heating solves this problem, but it needs to increase the circulating water pump, the water pump needs additional power consumption, the water pipe needs antifreeze treatment, troublesome debugging, secondary heat exchange, and low energy efficiency

The dehumidification of conventional air conditioners is cooling and dehumidification without reheating function. The dehumidification process causes the room temperature to drop, and the relative humidity does not drop significantly, so the dehumidification effect is not good, and the effect is even worse on re-humidity days. Ordinary dehumidifiers have relatively small power due to space constraints and long dehumidification time , multiple spaces require multiple
