Indirect evaporative chiller and mechanical refrigeration chiller combined cooling and air conditioning system

Abstract

The invention discloses a combined cooling air-conditioning system of an indirect evaporation chiller and a mechanical refrigeration chiller. A first-stage and a second-stage surface heat exchangers and a blower are arranged in order in a casing of an air processor from an air inlet to an air outlet, a water outlet pipe of the indirect evaporation chiller is connected to a water inlet of the first-stage surface heat exchanger of the air processor, a water outlet pipe of the first-stage surface heat exchanger is connected with a cooling water inlet of a traditional low-temperature chiller, a cooling water outlet of the traditional low-temperature chiller is connected with a water inlet of the indirect evaporation chiller, a chilled water outlet of the traditional low-temperature chiller is connected to a water inlet of the second-stage surface heat exchanger, a water outlet pipe of the second-stage surface heat exchanger is connected to an indoor tail-end water inlet located in an air-conditioning room, a water outlet pipe at the tail end in the air-conditioning room is connected with a chilled water inlet of the traditional low-temperature chiller, and an exhaust outlet of the blower leads to the air-conditioning room through a blast pipe. The combined air conditioning system not only can be used in dry heat regions but also can be used in moist heat regions, makes the best of refrigeration capacity of dry air energy, realizes the cascade utilization of energy, reduces the installed capacity and electric power load of equipment, improves the fresh air amount of the air-conditioning system, and improves the indoor air quality.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air-conditioning, and is suitable for application in various buildings in medium-humidity and high-humidity areas, in particular to a combined cooling and air-conditioning system of an indirect evaporative water chiller and a mechanical refrigeration chiller. 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 outdoor environments. [0003] At present, my country's building energy consumption has ex...

Problems solved by technology

However, in inland medium-humidity and high-humidity areas, due to the high moisture content and high relative humidity of the outdoor air, dry air energy evaporative cooling technology alone can not dehumidify the fresh air due to the limited temperature drop, and it is difficult to solve the heat dissipation of the air conditioning system And the task of dehumidification, so it has not received enough attention and application for a long time
