The invention discloses evaporative cooling- solar absorption refrigeration air conditioning system. The system comprises an indirect evaporative cooling subsystem and a solar absorption refrigerationsubsystem, wherein the indirect evaporative cooling subsystem and the solar absorption refrigeration subsystem are connected through an evaporator. The indirect evaporative cooling subsystem and thesolar absorption refrigeration subsystem are used for preparing lower-temperature air, intermediate heat exchange with freezing water is not needed, the heat exchange efficiency is improved, outdoor air is pre-cooled through the indirect evaporative cooling subsystem on the air supply side, so that the load borne by the solar absorption refrigeration subsystem is reduced, indoor low-temperature air is used as indirect evaporative cooler secondary air to take away absorption refrigeration cycle condensation heat on the air exhaust side, the condensation temperature can be reduced after a part of primary air heat is taken away, and the system refrigeration efficiency is improved on the basis of fully saving energy.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an evaporative cooling-solar absorption refrigeration and air-conditioning system. Background technique [0002] Evaporative cooling technology is an environmentally friendly and energy-efficient refrigeration technology. Indirect evaporative cooling is greatly affected by outdoor meteorological parameters. During the heat and humidity treatment process, it can only be treated with wet cooling. When it cannot meet the air supply requirements of the air conditioner, It can be used in combination with other refrigeration technologies to meet air conditioning needs, and indirect evaporative cooling can realize the precooling function of fresh air to reduce the load of other refrigeration equipment. There are three main types of indirect evaporative coolers: plate-fin type, tube type and heat pipe type. No matter what kind of heat exchanger, it has two ...
