Total heat recovery multi-cycle multipurpose air conditioning unit

Abstract

The invention provides a total heat recovery multi-cycle multipurpose air conditioning unit. The total heat recovery multi-cycle multipurpose air conditioning unit comprises a refrigerant loop and a second water cycle loop, wherein the refrigerant loop comprises a compressor, a third heat exchanger, a first heat exchanger, a first one-way valve, a liquid storage pot, a filter, a second one-way valve, a first expansion valve, a second heat exchanger and a gas-liquid separator which are successively connected with one another; the outlet of the gas-liquid separator is connected with the inlet of the compressor, and the third heat exchanger is a water-cooled heat exchanger; and the second water cycle loop comprises the third heat exchanger, a water box and a second water pump which are connected with one another in series so as to form the loop. In summer refrigeration, the second water pump is opened, a more efficient refrigeration effect is provided, and meanwhile, heat is used for preparing hot water, namely free hot water is obtained; and in winter, the sequence of heating and hot water preparation can be changed through an automation procedure. Therefore, the air conditioning unit has many functions.

Description

technical field [0001] The invention relates to the field of industrial refrigeration, in particular to an air conditioner. Background technique [0002] In the prior art, generally hotels and office buildings are equipped with large-scale central air conditioners and solar water heaters, two sets of equipment, so the pipelines are intricate and complicated. Generally, it can be seen that many office and commercial buildings need to use a whole floor to install these equipments, and professionals are needed Maintenance, therefore, equipment and maintenance costs are relatively high. [0003] In addition, most of the existing air conditioners use expensive refrigerants as the medium for transferring cooling and heat. In large-scale central air-conditioning equipment that needs to transfer cooling or heat over long distances, traditional central air-conditioning requires a large amount of refrigerant, which undoubtedly increases production. cost. It also increases the possib...

Problems solved by technology

[0004] Furthermore, in the existing central air conditioner, in order to reduce the complexity of the pipeline, the refrigeration or heating pipeline of the refrigerant is basically the same. Since the expansion valve and other equipment have different openings in cooling and heating, this affects the stability of the system. When the season changes, professional debugging is required
