Multifunctional novel outdoor unit integrating water cooling and air cooling heat exchange

Abstract

The invention relates to the field of air conditioner indoor units, in particular to an indoor unit integrating water cooling and air cooling heat exchange. The indoor unit comprises a compressor, a four-way reversing valve, a draught fan coil pipe, a second expansion valve and an air conditioner coil pipe and further comprises a spiral double-pipe heat exchanger, an adjusting water pump and a water-water heat exchanger. The spiral double-pipe heat exchanger is provided with an inner pipe pipeline and an outer pipe pipeline which exchange heat with each other. A refrigerant circulates in the inner pipe pipeline. Water circulates in the outer pipe pipeline. The draught fan coil pipe, the inner pipe pipeline, the second expansion valve, the air conditioner coil pipe, the four-way reversing valve and the compressor are sequentially connected to form a circulation loop, and the outer pipe pipeline, the adjusting water pump and the water-water heat exchanger are sequentially connected to form a circulation loop. Heat originally released into air is partially recycled, and energy consumption of a draught fan is reduced to a certain degree. Meanwhile, when a heat pump outdoor unit acts tobe used, the heat pump outdoor unit can be connected with multiple heat source water paths, a water source and air source composite heat pump becomes, the heat source utilization kinds are increased,the usage proportion can be balanced, and the functions of reducing energy consumption and saving space are achieved.

Description

technical field [0001] The invention relates to the field of air conditioner indoor units, in particular to an indoor unit integrating water cooling and air cooling for heat exchange. Background technique [0002] The structure difference of the outdoor unit of the conventional unit unit is small, and the function is single. In terms of space utilization, it is not very high. The heat exchange efficiency of air cooling is generally lower than that of liquid cooling (water cooling), and the energy consumption of fans that work for a long time cannot be ignored. When used as a part of the unit air conditioning system, it is only used to dissipate the heat transferred from the room through the fan coil unit. This part of the heat is lost to the ambient air, which not only affects the thermal balance of the environment, but is also a waste. Contents of the invention [0003] In order to solve the above problems, the present invention provides an outdoor unit integrating wat...
