Full variable-frequency speed-adjusting cold and warm type air-conditioning system for transportation device

Abstract

The invention discloses a full variable-frequency speed-adjusting cold and warm type air-conditioning system for a transportation device. An air conditioner is of an overhead unit. The air conditioner comprises a three-section type shell with two cover plates, and the shell is provided with an air discharge hole; and a variable-frequency speed-adjusting full-closed scroll compressor, an outdoor heat exchanger, a variable-frequency speed-adjusting condensing blower, an indoor heat exchanger with an auxiliary heat exchanger, a variable-frequency speed-adjusting ventilator, a power supply module, a control module and other system auxiliaries are arranged in the shell. The air conditioner self-adaptively adjusts the rotating speeds of the variable-frequency speed-adjusting full-closed scroll compressor, the variable-frequency speed-adjusting condensing blower and the variable-frequency speed-adjusting ventilator according to the indoor and outdoor temperature, temperature of the indoor heat exchanger and the outdoor heat exchanger and the intensity of the input power supply so as to achieve the effects of energy conservation and accurate control of temperature in a vehicle.

Description

Technical field: [0001] The invention relates to an air conditioner, in particular to a fully variable-frequency speed-regulating heating and cooling air conditioner that can be applied to various means of transportation. Background technique: [0002] The air-conditioning devices powered by the transportation device used in the existing transportation devices generally have unreasonable layout of the whole and its internal parts, occupy a large space, have backward energy regulation methods, have no heating function or use inefficient electric heating methods. [0003] Technical deficiencies involved in transport-powered air-conditioning units currently on the market for transport units: [0004] (1) The air conditioner has no adjustable device or adopts a backward adjustable method, which is inefficient and cannot stably control the temperature inside the car. [0005] (2) The condensing fan and ventilator of the air-conditioning device do not adjust the speed or adopt th...

AI Technical Summary

Problems solved by technology

[0004] (1) The air conditioner has no adjustable device or adopts a backward adjustable method, which is inefficient and cannot stably control the temperature inside the car

[0005] (2) The condensing fan and ventilator of the air-conditioning device do not adjust the speed or adopt the ordinary speed adjustment method, which cannot continuously adjust the wind speed, resulting in high energy consumption and low efficiency

[0006] (3) The air conditioner has no heating function or adopts ordinary electric heating heating method, which has low energy efficiency ratio and poor effect

[0007] (4) The air conditioner uses multiple compressors to form multiple system loops, which has high cost and low efficiency

[0009] In this way, the above-mentioned problems and defects also exist in the air-conditioning system for automobiles, and the complexity of its structure will reduce the efficiency of the entire air-conditioning system and increase the energy consumption of the system.
