Air conditioning system combined by indirect evaporation chiller plant and traditional mechanical refrigerating unit

Abstract

The invention discloses an air conditioning system combined by an indirect evaporation chiller plant and a traditional mechanical refrigerating unit. As for the air conditioning system, a surface heat exchanger, a water ring type compression refrigerating unit and a blower are successively arranged in the casing of an air handling unit (AHU) from an air inlet to an air outlet; the discharging tube of the indirect evaporation chiller plant is connected with the water inlet of the surface heat exchanger of the AHU; and one branch tube of a three-way connection of the discharging tube of the surface heat exchanger is connected with the water inlet of the water ring type compression refrigerating unit through a valve, the discharging tube of the water ring type compression refrigerating unit is connected with the water inlet of the indirect evaporation chiller plant, another branch tube of the three-way connection is connected on a pipeline of the discharging tube of the water ring type compression refrigerating unit through a valve, and the air outlet of the blower is led to an air conditioning room through a blast tube, wherein the pipeline of the discharging tube of the water ring type compression refrigerating unit is connected with the water inlet of the indirect evaporation chiller plant. The invention has the advantages that the applicable areas of evaporation refrigerating air conditioners is broadened, the air conditioning system can be used both in dry and hot areas and in damp and hot areas, the refrigerating capability of dry air energy is fully utilized, step utilization of energy is realized, the installed capability of equipment is lowered, the electric load of equipment is reduced, the fresh air requirement of the air conditioning system is increased and the indoor air quality is improved.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air conditioning, belongs to the air conditioning system of civil buildings and industrial buildings, is suitable for application in various buildings in areas with medium humidity and high humidity, and is especially a combination of an indirect evaporative water chiller and a traditional mechanical refrigeration unit air conditioning system. Background technique [0002] In the traditional air-conditioning system, the freon vapor compression refrigeration system uses electricity as the driving energy for refrigeration, while the lithium bromide absorption refrigeration uses gas or steam as the driving energy for refrigeration. , Excessive use of energy and resources, a large amount of greenhouse gas emissions lead to the intensification of the greenhouse effect, and many adverse effects such as sick building syndrome (Sick Building Syndrome, SBS) that destroy the indoor and out...
