Abstract

A receiver, a receiver assembly and a heat pump system. The receiver includes a first pipe, a second pipe and a third pipe leading to the cavity of the receiver, wherein the first pipe, the second pipe and the third pipe connect to a first load unit, a second load unit and a cold and heat source unit, respectively.

First claim

What is claimed is:

1. A receiver assembly for use in a refrigeration system, comprising:
a receiver;
a first pipe and a second pipe leading to a cavity of the receiver;
wherein, the receiver assembly further comprises:
a third pipe;
a first check valve connected between the first pipe and the third pipe;
a third pipeline connected to the third pipe;
a second pipeline connected to the second pipe;
a second check valve between the third pipeline and the second pipeline;
the first check valve and the second check valve allow fluid to flow from the first pipe to the second pipe;
wherein the first pipe connects to a first load unit, the second pipe connects to a second load unit, and a connection point for a cold and heat source unit is provided between the first check valve and the second check valve.

2. A heat pump system, comprising the receiver assembly according to claim 1 .

3. The heat pump system according to claim 2 , wherein the first load unit and/or the second load unit are selected from an air conditioning unit, a hot water generating unit, a floor heating unit, and a refrigerator cabinet unit.

4. The heat pump system according to claim 2 , wherein the first load unit is a refrigerator cabinet unit, and the second load unit is an air conditioning unit.

5. A heat pump system comprising:
a receiver including:
a first pipe and a second pipe leading to a cavity of the receiver;
a third pipe:
a first check valve connected between the first pipe and the third pipe:
a third pipeline connected to the third pipe:
a second pipeline connected to the second pipe:
a second check valve between the third pipeline and the second pipeline:
the first check valve and the second check valve allow fluid to flow from the first pipe to the second pipe:
wherein a cold and heat source unit comprises: a compressor, a switching device, a heat exchanger and a throttling device, and the receiver and the cold and heat source unit are integrated in a same outdoor unit housing, or arranged separately.

6. A heat pump system comprising:
a receiver including:
a first pipe and a second pipe leading to a cavity of the receiver;
a third pipe;
a first check valve connected between the first pipe and the third pipe;
a third pipeline connected to the third pipe;
a second pipeline connected to the second pipe;
a second check valve between the third pipeline and the second pipeline;
the first check valve and the second check valve allow fluid to flow from the first pipe to the second pipe;

wherein the receiver is placed upright, and the first pipe and the second pipe extend to the bottom of the receiver.

7. The heat pump system according to claim 2 , wherein the heat pump system is capable of operating in one, multiple, or all of the following modes:
a first mode in which the first load refrigerates and the second load shuts down;
a third mode in which the first load shuts down and the second load refrigerates;
a fourth mode in which the first load shuts down and the second load heats;
a fifth mode in which the first load refrigerates and the second load refrigerates;
a seventh mode in which the first load refrigerates and the second load heats;
wherein, the receiver functions in any of the above modes.

8. The heat pump system according to claim 7 , wherein in the fifth mode, refrigerant passes from the second load unit through the second pipe, the receiver and the first pipe, and flows to the first load unit.
