Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment, but is not limited to the content on the description.

[0014] The invention discloses an air-conditioning system, comprising: a refrigerant compression circulation pipeline 10, a diffuser pipeline 20, the refrigerant compression circulation pipeline 10 includes an indoor side heat exchanger 12, a first The refrigerant pipeline 13 and the diffuser pipeline 20 are arranged in parallel on the first refrigerant pipeline 13 .

[0015] According to the law of mass conservation and energy conservation, the refrigerant flows through the diffuser pipeline, the area increases, the flow velocity decreases, the kinetic energy decreases, the resistance is ignored, the enthalpy value increases, and the impact of gas molecules on the container wall increases, thereby Therefore, the diffuser pipe is connected in parallel on the main circuit of the system. When the heat pump air conditioner is started...

Abstract

The invention discloses an air-conditioning system. The air-conditioning system comprises a refrigerant compression and circulation pipeline and a diffusion pipeline, wherein the refrigerant compression and circulation pipeline comprises an indoor side heat exchanger and a first refrigerant pipeline communicated with an inlet of the indoor side heat exchanger; and the diffusion pipeline is arranged on the first refrigerant pipeline in parallel. According to the law of conservation of mass and the law of conservation of energy, a refrigerant flows through the diffusion pipeline, so that the area is increased, the flow rate and the kinetic energy are reduced, the resistance is ignored, the enthalpy value is increased, the impact of gas molecules on a container wall is increased, and accordingly, the pressure is increased. Therefore, a diffusion pipe is connected in parallel with a system circulation main line; and when a heat pump air-conditioner is started at a low temperature in a coldregion, the system pressure and temperature are quickly increased, the cold air prevention time is shortened, and the comfort of a human body and the reliability of a heat pump technology applied tothe cold region are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system. Background technique [0002] When the heat pump air conditioner is used for heating in low-temperature areas, when the unit stands still for a long time, the pressure and temperature of the refrigerant in the system are very low. In this case, when the compressor starts, the suction and exhaust pressure is very low, and the indoor side blows cold air. In order to avoid the cold air blowing out and causing discomfort to the human body, some air-conditioning companies currently turn off the indoor side fan when starting at low temperature to solve this problem. Prevent cold wind from blowing out. If the indoor side fan is turned off for a long time, it will affect the comfort of the human body, and it will cause users to mistakenly think that the air conditioner is bad; if the anti-cold wind time is short, the system pressure and temperature a...
