Non-fuel air conditioner heating system for crane and method thereof

Abstract

The invention discloses a non-fuel air conditioner heating system for a crane and a method thereof. The non-fuel air conditioner heating system comprises an outdoor unit assembly, wherein the outdoor unit assembly comprises a hydraulic valve, a hydraulic motor, a gear pump set and an oil tank; hydraulic oil conveyed by a crane hydraulic pump is input into the hydraulic motor through the hydraulic valve, a shaft of the hydraulic motor is directly connected with a shaft of the gear pump set located in the oil tank, and when the hydraulic motor operates, the gear pump set operates; a first pump in the gear pump set heats the heat conduction oil in the oil tank, a second pump conveys the heat conduction oil into a warm air core body in an indoor unit assembly through a pipeline, so that the temperature of the warm air core body is increased, and the heat conduction oil returns to the oil tank from the pipeline connected with the warm air core body; an air feeder blows air to the warm air core body to transmit heat to a control chamber. The non-fuel air conditioner heating system for the crane is simple in structure, under the non-combustion condition, mechanical energy is effectively converted into heat energy through acting, the heat conduction oil serves as a heat conduction medium, heating in the control chamber is achieved, and the non-fuel air conditioner heating system is more environmentally friendly and saves resources.

Description

technical field [0001] The invention relates to the field of engineering machinery air conditioners, in particular to a non-fuel air conditioner and heating system for cranes and a method thereof. Background technique [0002] For construction machinery such as truck cranes, off-road tire cranes, crawler cranes and other types of heavy construction machinery, the heating of the control room mainly uses fuel heaters. The principle is that the fuel heater burns diesel to heat the circulating water and send it to the control room In the warm air core of the indoor unit assembly, the hot air is delivered to the control room by the blower in the indoor unit assembly. Since the fuel oil heater needs to burn diesel continuously during the working process, on the one hand, it consumes energy and is uneconomical, on the other hand, it is not conducive to environmental protection, and the exhaust gas emitted will pollute the air; and when the construction machinery is working, the rot...

AI Technical Summary

Problems solved by technology

Since the fuel oil heater needs to burn diesel continuously during the working process, on the one hand, it consumes energy and is uneconomical, on the other hand, it is not conducive to environmental protection, and the exhaust gas emitted will pollute the air; and when the construction machinery is working, the rotary motor on the crane needs oil supply and Oil return. At present, the oil supply pump for the rotary motor will be greater than the oil demand of the rotary motor, causing some hydraulic oil to be in a surplus state, which cannot be fully utilized, and also causes a waste of resources.
