Benefits of technology

The present patent seeks to provide an accumulator that can reduce the accumulation of lubricating oil. Additionally, it also aims to provide a heat pump system with an accumulator that can achieve the same.

Problems solved by technology

Such an accumulator has a relatively high material cost and manufacturing cost.
However, when a single-pipe accumulator is used, it is prone to a phenomenon whereby lubricating oil entering the accumulator with the refrigerant is retained in and builds up in the accumulator, which affects the service life of the heat pump system by causing a loss of lubricating oil in the compressor.
This in turn impacts on system reliability.

Embodiment Construction

[0010]Referring to FIGS. 1 and 2, one embodiment of an accumulator assembly in accordance with the present concept is illustrated. The accumulator assembly 100 comprises an accumulator tank body 110 and a connecting pipe 120 coupled thereto. Here, an inlet and outlet port 111 is provided at the bottom portion 110a of the accumulator tank body 110, and the key point is that the inlet and outlet port 111 is flush with the bottom portion 110a of the accumulator tank body 110. At the same time, a first end 120a of the connecting pipe 120 is connected to the inlet and outlet port 111, and a second end 120b thereof is used for connection to an air conditioning system. In certain scenarios, the air conditioning system is a heat pump system. Under this arrangement, since the inlet and outlet port is flush with the bottom of the accumulator tank body, in the case where all the refrigerant is needed for operation of the system, the refrigerant and lubricating oil accumulated in the accumulato...

Abstract

An accumulator assembly and a heat pump system. The accumulator assembly comprises: an accumulator tank body, wherein an inlet and outlet port is disposed at the bottom of the tank body and is flush therewith; and a connecting pipe, having a first end connected to the inlet and outlet port, and a second end for connection to an air conditioning system. According to the accumulator assembly of the present invention, because the inlet and outlet port is flush with the bottom of the accumulator tank body, in the case in where all the refrigerant is needed for the operation of the system, refrigerant and lubricating oil accumulated within the accumulator tank body can be completely drained from the tank body, thus ensuring sufficient refrigerant to satisfy load demand while simultaneously ensuring sufficient lubricating oil to satisfy the lubrication requirements of the compressor.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of air conditioning, and more particularly to an accumulator for a heat pump system.BACKGROUND ART[0002]At present, heat pump systems having both cooling and heating functions are widely used in various commercial and domestic applications such as hospitals, shopping malls, and homes. In practical application, heat pump system condensers typically employ coiled heat exchangers to achieve more substantial contact and heat transfer with air, whereas evaporators typically utilize plate heat exchangers for maximal heat exchange between a primary and secondary refrigerant (e.g. water). The working principle involves switching the heat exchange flow path in the heat pump system, so that in the cooling mode the coiled heat exchanger serves as a condenser and the plate heat exchanger serves as an evaporator. whereas in the heating mode, the coiled heat exchanger serves as an evaporator and the plate heat exchanger serves as a c...
