Refrigeration and dehumidifying type air-conditioning device provided with all cold and heat sources and capable of preparing cold and hot water

Abstract

The invention relates to a refrigeration and dehumidifying type air-conditioning device provided with all cold and heat sources and capable of preparing cold and hot water. The refrigeration and dehumidifying type air-conditioning device comprises a compressor, a first refrigeration or heating device, a second refrigeration or heating device, a first cold exchange or heat exchange device, a second cold exchange or heat exchange device, a humidifying module, a reheating module, a throttling valve and a rotary wheel heat recycling module, wherein new air passes through a rotary wheel in the rotary wheel heat recycling module to be cooled, dehumidified or heated, then passes through the first refrigeration or heating device, the humidifying module and the reheating module, is mixed with mixed air and enters the second refrigeration or heating device to be cooled and dehumidified. Most of the new air is fed into a room, and the left is returned to the rotary wheel in the rotary wheel heat recycling module, so that energy conversion is realized. The first cold exchange or heat exchange device outputs cold or hot water. The refrigeration and dehumidifying type air-conditioning device resolves the problems that a common full-air air-conditioning system is high in energy consumption, large in building occupied space, long in construction cycle, complex in process and the like.

Description

technical field [0001] The invention relates to the technical field of air-conditioning units in civil and industrial projects, in particular to a refrigeration and dehumidification air-conditioning device with all cold and heat sources and for preparing cold and hot water. technical background [0002] At present, energy saving and emission reduction and building a resource-saving society have become a very important task at present. Building energy consumption accounts for about 30% of the total energy consumption of the whole society, and the energy consumption of air-conditioning systems accounts for 40-40% of the total energy consumption of buildings. 60%, therefore, reducing the energy consumption of the central air-conditioning system has become an important direction of my country's energy saving and emission reduction. Limited to the current technical level, the actual effective use area of ​​civil buildings and industrial projects is about 75-85%, of which the air-c...

AI Technical Summary

Problems solved by technology

[0004] 1. There must be centralized cold source and heat source equipment;

[0005] 2. Due to the existence of (1), the building must provide a certain cold source and heat source room, which reduces the effective utilization rate of the building area;

[0006] 3. With centralized cold source and heat source equipment, there is still the problem of difficult system adjustment when some areas have loads and some areas have no loads. In this case, air conditioning equipment (mainly cold and heat source equipment, circulation pumps, etc.) inefficient state

This is also a mechanical defect of why the energy consumption of the conventional air conditioning system is very high and d
