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 heat pump system, comprising:
a receiver including a first pipe, a second pipe and a third pipe leading to a cavity at a bottom of the receiver;
a first load unit directly connected to the first pipe of the receiver;
a second load unit directly connected to the second pipe of the receiver; and
a cold and heat source unit directly connected to the third pipe of the receiver.

2. The heat pump system according to claim 1 , 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.

3. The heat pump system according to claim 1 , wherein the first load unit is a refrigerator cabinet unit, and the second load unit is an air conditioning unit.

4. The heat pump system according to claim 1 , wherein the 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.

5. The heat pump system according to claim 1 , 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 second mode in which the first load heats 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 sixth mode in which the first load heats and the second load heats;
a seventh mode in which the first load refrigerates and the second load heats;
an eighth mode in which the first load heats and the second load refrigerates;
wherein, the receiver functions in any of the above modes.
