Abstract

The invention discloses a high-temperature heat pump liquid storage device and a high-temperature heat pump hot water machine comprising the same. The high-temperature heat pump liquid storage device comprises a device body, a liquid storage cavity defined by the device body, a liquid inlet pipe inserted in the liquid storage cavity and used for refrigerants to flow in the liquid storage cavity, and a liquid outlet pipe inserted in the liquid storage cavity and used for the refrigerants to flow out of the liquid storage cavity. The high-temperature heat pump liquid storage device further comprises a blind pipe arranged in the liquid storage cavity and located below the liquid inlet pipe. The blind pipe is a pipe body, the bottom end of the blind pipe is sealed, and an opening is formed in the top end of the blind pipe. The area of the opening is larger than the cross section area of the liquid inlet pipe. Gas-liquid coexisting refrigerants which enter the liquid storage cavity through the liquid inlet pipe can be subjected to gas-liquid separation in the liquid storage device, and the problem that gas-state refrigerants flow out from the liquid outlet pipe is solved. The high-temperature heat pump liquid storage device is used in cooperation with a heat pump system, so that electric energy consumption of the heat pump system is effectively lowered, and using cost is reduced. The high-temperature heat pump liquid storage device has the advantages of being simple in structure, reasonable in design, strong in practicability, and the like.

Description

technical field

[0001] The present invention relates to the technical field of a liquid accumulator, more specifically, relates to a high-temperature heat pump liquid accumulator used in conjunction with a high-temperature heat pump system, which can effectively improve the operation stability of the heat pump system; The high-temperature heat pump water heater of the high-temperature heat pump liquid storage. Background technique

[0002] The accumulator is an auxiliary element of the heat pump system, which is usually connected with the compressor and is used to store liquid refrigerant. In the high temperature heat pump system, the liquid inlet of the liquid inlet pipe of the liquid receiver is connected with the outlet of the condenser, and the liquid outlet of the liquid outlet pipe is connected with the expansion valve.

[0003] In a high-temperature heat pump system, due to the high temperature at the condensing end, the condensing effect is poor, and the refrigerant...

Examples

Embodiment 1

[0029] Embodiment 1 of the present invention provides a high-temperature heat pump liquid accumulator, which is intended to enable the liquid accumulator to have both the liquid storage function and the gas-liquid separation function, so as to solve the problem that the gaseous refrigerant flowing into the liquid accumulator flows out from the liquid outlet pipe and Entering the expansion valve, it seriously affects the throttling effect of the expansion valve, thereby affecting the stability of the high-temperature heat pump system operation, which in turn leads to the problem that the energy-saving effect of the high-temperature heat pump system is greatly reduced. The present embodiment will be described in detail below in conjunction with the accompanying drawings.
