Cooling and heating special unit of heat source tower

Abstract

The invention discloses a cooling and heating special unit of a heat source tower, comprising a water heat exchanging system and a refrigerant heat exchanging switching system, wherein the refrigerant heat exchanging switching system includes a compressor, a heat exchanger specialized for the heat source tower, a functional heat exchanger, an oil separator, an electronic expansion valve, and a dry filter. A cooling loop is formed by connecting the compressor, the oil separator, the heat exchanger specialized for the heat source tower, the dry filter, the electronic expansion valve and the functional heat exchanger in turn through pipelines; and a heating loop is formed by connecting the compressor, the oil separator, the functional heat exchanger, the dry filter, the electronic expansion valve, and the heat exchanger specialized for the heat source tower in turn through pipelines. The cooling and heating special unit for the heat source tower not only has the advantages of energy saving, high efficiency, environmental protection, realization of possessing of three functions of cooling, heating and hot water providing by one system, and realization of low carbon, environmental protection, recycling economy and the like, but also has such significant effects as simple engineering construction, convenient operation, high efficiency, low cost, and reliable handling performance.

Description

technical field [0001] The invention relates to an air conditioning unit, in particular to a cooling and heating special unit system for a heat source tower. Background technique [0002] The traditional air conditioning unit that uses the heat source tower for cooling and heating is composed of two parts: a waterway heat exchange system and a refrigerant heat exchange system. The waterway heat exchange system is mainly composed of unit heat exchangers, heat source towers, and indoor air conditioners. In order to realize the two functions of heating in winter and cooling in summer, complex pipeline connections are often used, and many valves are installed on the pipelines for switching control, which will bring more troubles to the engineering construction. , It is very inconvenient to operate, low in efficiency, and increases costs; at the same time, because the heat source tower system has antifreeze in the water system circuit on the side of the tower in winter, if the sw...

[0002] The traditional air conditioning unit that uses the heat source tower for cooling and heating is composed of two parts: a waterway heat exchange system and a refrigerant heat exchange system. The waterway heat exchange system is mainly composed of unit heat exchangers, heat source towers, and indoor air conditioners. In order to realize the two functions of heating in winter and cooling in summer, complex pipeline connections are often used, and many valves are installed on the pipelines for switching control, which will bring more troubles to the engineering construction. , it is very inconvenient to operate, low in efficiency, and increases costs; at the same time, since the heat source tower system has antifreeze in the water system circuit on the side of the tower in winter, if the switch is not in place, it will cause corrosion to the indoor system

Under the background that today's society pays full attention to the natural environment and climatic conditions, this traditional technology obviously cannot meet the strategic actions of energy conservation, emission reduction, ecological environment, low-carbon economy, and circular economy proposed by our country. It is necessary to propose new technologies solutions to solve or improve traditional process technology
