Abstract

The invention provides a throttling multi-port expansion valve assembly and a vehicle. The throttling multi-port expansion valve assembly comprises a valve body, the valve body is provided with a valve inlet, a first valve outlet and a second valve outlet, and a capillary throttle pipe is arranged behind the valve inlet. The valve inlet is connected with an in-vehicle condenser outlet, the first valve outlet is connected with an evaporator inlet, and the second valve outlet is connected with an air compensating port of a gas compensating and enthalpy increasing compressor. The valve body is provided with a flow regulating mechanism, and the flow regulating mechanism includes a driving rod. The driving rod is in contact with a transmission sleeve rod, and the transmission sleeve rod is in contact with a valve rod. A throttling hole is formed in front of the valve rod. The throttling multi-port expansion valve assembly improves the valve body, so that an expansion valve has two-stage throttling function and has the functions of a gas-liquid separator, it is beneficial to eliminating a complicated flash evaporator and reducing an expansion valve in an automobile gas compensating and enthalpy increasing heat pump air-conditioning system, the pipeline design is optimized and the cost is reduced, and economical and practical properties are achieved.

Description

technical field [0001] The invention relates to a vehicle expansion valve, in particular to a throttling multi-port expansion valve assembly. In particular, a two-stage throttling three-port electronic expansion valve assembly and a vehicle. Background technique [0002] Electric vehicles are attracting more and more attention. Facing the problem of high heating power consumption in winter, heat pump systems have been extensively studied due to their high efficiency and energy saving. However, heat pump systems also have the problems of low temperature start-up and insufficient heating performance. One of the solutions is to increase the heating capacity of the heat pump system by supplementing air to increase enthalpy. Patent document CN106016811B discloses an electric vehicle air-conditioning heat pump system with an economizer, in which the first four-way reversing valve and the second four-way reversing valve are respectively set as refrigerant flow switching valve grou...
