Flash tank, heat pump system

Abstract

The invention provides a flash tank and a heat pump system. The flash tank comprises a housing and a wire net, wherein the housing is provided with an outlet pipe; a liquid dividing surface of the wire net and the axis of the outlet pipe form an included angle alpha, 90 DEG<alpha<180 DEG; the wire net is arranged in the housing and on the intake path of the outlet pipe. According to the flash tankand the heat pump system of the present invention, the phenomenon that the liquid film on the wire net is torn and re-entangled in the airflow during the gas-liquid separation process, and the secondary air-liquidization of the airflow can be effectively prevented. The flash tank improves the gas-liquid separation efficiency and effect.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a flasher and a heat pump system. Background technique [0002] When traditional air source heat pumps operate in low-temperature environments in winter, there are problems such as high exhaust temperature and high pressure ratios, which adversely affect the operating performance of the system. Due to their superior performance in low-temperature environments, the two-stage compression system It is considered to be an effective improvement scheme; although the two-stage compression has a certain effect on reducing the exhaust temperature of the compressor, there is still the problem that the exhaust temperature exceeds the standard under extremely low temperature conditions, such as R32 refrigerant at -30°C Under working conditions, the exhaust temperature of the system exceeds 100°C, and long-term operation has a great impact on the reliability of the compre...

[0002] When traditional air source heat pumps operate in low-temperature environments in winter, there are problems such as high exhaust temperature and high pressure ratios, which adversely affect the operating performance of the system. Due to their superior performance in low-temperature environments, the two-stage compression system It is considered to be an effective improvement scheme; although the two-stage compression has a certain effect on reducing the exhaust temperature of the compressor, there is still the problem that the exhaust temperature exceeds the standard under extremely low temperature conditions, such as R32 refrigerant at -30°C Under working conditions, the exhaust temperature of the system exceeds 100°C, and long-term operation has a great impact on the reliability of the compressor; the intermediate air supply technology can reduce the temperature of the refrigerant in the working chamber of the compressor and increase the Heating performance has become an effective measure to reduce the exhaust temperature of the heat pump system and ensure the heating performance under low temperature conditions

At present, the intermediate gas supply technology is mainly realized by the flasher. The flasher is usually equipped with screens, baffles and other components to strengthen flashing and separation. The current layout of the screen is horizontal. This arrangement makes The surface of the screen is very easy to accumulate liquid film, and the liquid film is torn under the action of air flow, resulting in secondary carryover of liquid droplets, which leads to poor gas-liquid separation effect of the flasher, serious phenomenon of gas-supplementing and liquid-carrying, and reduces compression In addition, the current flasher manufacturing process is complicated, and it is inconvenient to install components such as strengthening flashing and separation in the flashing barrel. Most of them use cutting barrels to arrange strengthening components and then weld them together, resulting in reduced production and assembly efficiency.
