Cool storage type low energy consumption airplane ground air conditioner

Abstract

The invention relates to a cool storage type low energy consumption airplane ground air conditioner. The cool storage type low energy consumption airplane ground air conditioner comprises a condenser,a first compressor set and a second compressor set which are connected with the condenser simultaneously, a plate heat exchanger which is connected with the condenser, the first compressor set and the second compressor set simultaneously, a primary evaporator and a secondary evaporator which are connected with the condenser respectively, a circulating water pump and an air blower, wherein the circulating water pump is used for conveying cooling capacity to a cool storage box through the plate heat exchanger during cool storage and conveying cooling capacity to a surface air cooler through thecool storage box during cool discharge; an exhaust inlet of the air blower is formed in the lower part of the primary evaporator, an air outlet is connected with an inlet of an air flue, the surfaceair cooler, the secondary evaporator and a heater are arranged inside the air flue along the direction of an air flow in sequence, and an air outlet of the air flue is connected into the interior of an airplane through an air hose and a standard joint. Peak shaving is realized, cool storage and cool discharge are carried out according to practical situation, airplane high-power cooling capacity requirement can be met by using the two compressor sets, and the effects of saving energy and reducing energy consumption are reached.

Description

technical field [0001] The invention relates to the technical field of aircraft ground air conditioners, in particular to a cold storage type low energy consumption aircraft ground air conditioner. Background technique [0002] Existing airport stands are mainly divided into two types: corridor bridge and remote stand. During the period of the airport bridge and remote stand, the aircraft mainly uses ground air-conditioning equipment to provide air-conditioning services for the aircraft cabin and instrumentation equipment. The corridor bridge usually The configured power supply is relatively sufficient to meet the operating power requirements of the ground air-conditioning equipment; the power supply configured for remote parking is relatively low, about 1 / 3 of the operating power required by the ground air-conditioning equipment, and high-power compressor units cannot be used. The air-conditioning equipment for remote machine position support uses internal combustion units,...
