Refrigeration dehumidifying all-air conditioning unit with all cold and heat sources

Abstract

The invention relates to the technical field of air conditioners, in particular to a refrigeration dehumidifying all-air conditioning unit with all cold and heat sources. The refrigeration dehumidifying all-air conditioning unit comprises a cold or heat source unit, an all-air heat and moisture treatment unit and a heat recovery unit, the all-air heat and moisture treatment unit comprises a fresh air heat and moisture treatment unit and a mixed air heat and moisture treatment unit, the cold or heat source unit is sued for providing all cold or heat quantity for treatment of air heat and moisture load, the temperature of the fresh air can be reduced by the fresh air heat and moisture treatment unit, fresh air can be dehumidified or heated and humidified by the fresh air heat and moisture treatment unit, the temperature of the mixed air of return air and the fresh air can be reduced by the mixed air heat and moisture treatment unit, and the mixed air can be dehumidified or heated by the mixed air heat and moisture treatment unit. By the aid of the structure, cold or heat source devices, cold or heat source machine rooms and transmission and distribution systems among the cold and heat sources and the air conditioning unit can be omitted, cold water and heat water transmission and distribution energy consumption of an air conditioning system is completely omitted, the refrigeration dehumidifying all-air conditioning unit solves the problem of difficulty in distribution and adjustment of cold and heat quantity among the concentrated cold and heat sources and air conditioning zones, and energy is remarkably saved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a refrigeration and dehumidification full-air air conditioning unit with all cold and heat sources. Background technique [0002] At present, the conventional all-air air-conditioning system is composed of cold source and heat source, cold and hot water distribution system, all-air air-conditioning unit, terminal tuyere device and automatic control system. Conventional full-air air conditioning system, the main problems include: [0003] 1. There must be centralized cold source and heat source equipment, and there must be cold water and hot water transmission and distribution systems (circulation pumps, sub-collectors and water pipelines), so there is a large energy consumption for transmission and distribution; [0004] 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 t...

AI Technical Summary

Problems solved by technology

[0003] 1. There must be centralized cold source and heat source equipment, and there must be cold water and hot water transmission and distribution systems (circulation pumps, sub-collectors and water pipelines), so there is a large energy consumption for transmission and distribution;

[0004] 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;

[0005] 3. Due to the existence of (1), the construction and commissioning of the transmission and distribution system (pumps, pipelines) must be completed, and there are problems of large construction volume and long construction period;

[0006] 4. With centralized cold source and heat source equipment, there is still the problem of system adjustment difficulties 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 why the energy consumption of conventional air conditioning systems is high and difficult to reduce - that is, it cannot adapt to the demand conditions where only local areas have air conditioning and heating;

[0007] 5. Since the entire air-conditioning system involves refrigeration equipment, heating equipment, circulation pumps, all-air air-conditioning units, fresh air units + fan coil units, etc., there are many system links, which brings problems such as complex design of the automatic control system, and difficulties in actual management and coordination.
