Split depressurization water/ground energy cold and warm domestic hot water integrated central air conditioning unit

Abstract

The invention is applicable to the field of air conditioners and provides a split depressurization water / ground energy cold and warm domestic hot water integrated central air conditioning unit, comprising a compressor, a heat recycling heat exchanger, an electromagnetic valve, split depressurization water / ground energy heat exchangers, an electromagnetic three-way valve and a using side heat exchanger which are connected in series by pipelines. In the split depressurization water / ground energy cold and warm domestic hot water integrated central air conditioning unit, water or soil is adopted as a direct cold and hot source of a refrigerant, and the depressurization heat exchangers which are scattered in a water body and the soil are adopted as condensers for directly condensing the refrigerant to release heat directly in the refrigerating season; and in the season of making domestic hot water and heating, the depressurization heat exchangers which are scattered in a water body and thesoil are adopted as evaporators to directly evaporate the refrigerant to absorb heat, so that the heat exchanging efficiency is improved substantially. The central air conditioning unit firstly adopts a long-distance fluorine path to directly condensate or evaporate in the water body and the soil, overcomes the problem of heat exchanging efficiency loss of the existing water and ground source heat pump due to multiple times of heat exchange of middle media, the energy efficiency ratio and the stability of a system are improved by times, and the application range of a water and ground energy heating pump can be expanded greatly.

Description

technical field [0001] The present invention belongs to the field of air-conditioning equipment, and in particular relates to the field of a central air-conditioning unit with integrated step-down water / ground energy heating and domestic hot water. A central air-conditioning unit that uses water energy or ground energy to directly exchange heat with refrigerants in the soil, and integrates heating and cooling domestic hot water. Background technique [0002] Building energy consumption has accounted for more than 40% of the total energy consumption of the society, and the energy consumption of heating, cooling and domestic hot water in building energy consumption accounts for 70% of building energy consumption. Therefore, using clean and renewable energy to reduce energy consumption and emissions for heating, cooling and domestic hot water production is the key to energy saving and emission reduction for the whole society. [0003] At present, the ground source heat pump ai...
