Novel variable-frequency stable refrigeration system

Abstract

The invention provides a novel variable-frequency stable refrigeration system. The novel variable-frequency stable refrigeration system is characterized by comprising an air inlet, a filter, a first evaporation chamber, compressors, a condensation pipe, a first air channel, variable-frequency air blowers, motors, second evaporation chambers, second air channels and outlets, wherein the air inlet is arranged on the first evaporation chamber positioned at the upper end of the system; the filter is arranged below the air inlet; one compressor is arranged inside the first evaporation chamber and communicates with the first air channel via the condensation pipe; the two sides of the first air channel each communicate with the corresponding variable-frequency air blower; the variable-frequency air blowers are separately controlled and driven by the corresponding variable-frequency motors at the two sides; the first air channel communicates with the second evaporation chambers through the variable-frequency air blowers; two second evaporation chambers are arranged symmetrically; the two second evaporation chambers each communicate with the corresponding second air channel; and the end opening of each second air channel is provided with one outlet. The novel variable-frequency stable refrigeration system provided by the invention has the advantages of being reasonable in design, high in efficiency, capable of saving energy, high in adjustment precision, high in intelligence degree, compact in structure, small in size, light in weight, high in safety, stable and reliable in operation, capable of saving power and reducing environmental pollution, high in output air temperature adjustment precision, good in cooling effect, good in running reliability and long in service life, and has important economic and social significances.

Description

technical field [0001] The invention relates to the field of aircraft ground air-conditioning equipment, in particular to a frequency conversion high-precision aircraft ground air-conditioning unit, and in particular provides a novel frequency conversion stable refrigeration system. Background technique [0002] In the existing general aircraft ground air-conditioning unit, the fresh air passes through the multiple refrigeration systems of the unit for direct evaporative cooling or heating by electric heaters, and then the cold or hot air passes through the air-conditioning outlet of the aircraft air-conditioning through the insulated delivery hose and quick connector. It is sent into the aircraft cabin and cockpit to provide processed cooling air with a certain flow rate, temperature and pressure for the aircraft parked at the airport. However, due to the fixed-frequency refrigeration system and non-high-precision control method used by the ground air-conditioning units of t...
