Hoisting air conditioner special for passenger compartment

Abstract

The invention discloses a hoisting air conditioner special for a passenger compartment. The hoisting air conditioner special for the passenger compartment is characterize in that the hoisting air conditioner comprises a hoisting component, a filter, an electric heating element, a compressor, a first evaporation chamber, a first air duct, a box body, an air blower, a second air duct, flow draught fans and a second evaporation chamber; the hoisting component is arranged at the upper end of the box body, and the one or two or three flow draught fans are connected to the lower end of the box body; the first evaporation chamber and the second evaporation chamber are arranged in the box body; the filter and the electric heating element are sequentially arranged at the left end of the first evaporation chamber; the compressor is arranged on the side wall of the first evaporation chamber; the first evaporation chamber communicates with the second evaporation chamber through the first air duct and the second air duct; and the air blower is arranged at the connection position of the first air duct and the second air duct. The hoisting air conditioner special for the passenger compartment has the beneficial effects that the structure is reasonable and compact; design is ingenious; the occupied space is small; safety and reliability are achieved; stability is high; the cooling effect is good; temperature adjustment precision is high; and the hoisting air conditioner meets energy conservation and environment protection policies initiated by the state. Great economic significance and social significance are achieved.

Description

technical field [0001] The invention relates to the field of aircraft ground air conditioning equipment, and in particular provides a special hoisting air conditioner for a cabin. Background technique [0002] In the existing aircraft ground air-conditioning unit, after the fresh air is directly evaporative cooling or electric heater heating treatment of multiple refrigeration systems of the unit, the cold air or hot air is sent in through the air-conditioning outlet of the aircraft air-conditioning through the insulated delivery hose and quick connector. The aircraft cabin and cockpit provide processed cooling air with a certain flow rate, temperature and pressure for the aircraft parked at the airport. However, since the ground air conditioning units of this type of aircraft adopt a fixed-frequency refrigeration system and a non-high-precision control method, part-load operation High energy consumption, high operating costs, serious environmental pollution, does not confor...

[0002] In the existing aircraft ground air-conditioning unit, after the fresh air is directly evaporative cooling or electric heater heating treatment of multiple refrigeration systems of the unit, the cold air or hot air is sent in through the air-conditioning outlet of the aircraft air-conditioning through the insulated delivery hose and quick connector. The aircraft cabin and cockpit provide processed cooling air with a certain flow rate, temperature and pressure for the aircraft parked at the airport. However, since the ground air conditioning units of this type of aircraft adopt a fixed-frequency refrigeration system and a non-high-precision control method, part-load operation High energy consumption, high operating costs, serious environmental pollution, does not conform to the energy conservation and environmental protection policies advocated by the state, the multi-compressor control method can only be used to control the outlet air temperature by starting and stopping the compressors, so that it can control the outlet air temperature The precision is low. Every time a compressor is turned on and off, the output air temperature and cooling capacity output are extremely unstable, which makes the cooling effect inside the aircraft cabin poor. The cooling effect is not good, which reduces the operational reliability and service life of the precision equipment inside the aircraft cabin, affects the safety performance and service life of the aircraft, and at the same time makes the environment comfortable for the personnel in the cabin low, and even affects the safety of the aircraft operators. Mental state, which indirectly affects the safe driving of the aircraft
