Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 2, an air source heat pump unit waterway system includes a refrigerant supply tank 3, a refrigerant supply pipe 4, at least two heat exchangers 5, and a refrigerant discharge pipe 6, wherein one end port of the refrigerant supply pipe 4 is opened, the other end port is closed by a plug, an output end of the refrigerant supply tank 3 is connected with one end port of the refrigerant supply pipe 4, one end port of the refrigerant discharge pipe 6 is opened, the other end port is closed by a plug, a refrigerant inlet 51 of the heat exchanger 5 is connected with the refrigerant supply pipe 4, and a refrigerant outlet 52 of the heat exchanger is connected with the refrigerant discharge pipe 6. The refrigerant inlets 51 of all the heat exchangers are connected with the refrigerant supply pipe 4, and the refrigerant outlets 52 of all the heat exchangers are connected with the refrigerant discharge pipe 6, so that the temperature of the refrigerant in the refrigerant inlets 51 of all the heat exchangers is ensured to be consistent, and the temperature of the refrigerant of the heat exchanger which is farther away from the inlet of the refrigerant supply pipe 4 is not higher. Compared with the prior art, when a plurality of heat exchangers are used, the heat exchange rate is not reduced.
The refrigerant supply pipe 4 is located above the heat exchanger 5, and the refrigerant discharge pipe 6 is located below the heat exchanger 5. Through the arrangement, the refrigerant flows from top to bottom under the action of gravity, so that the flowing speed of the refrigerant is improved.
As shown in fig. 3, for the first improved structure of the present invention, the present invention further includes a supercharger 7, and the refrigerant supply pipe 4 is connected to the supercharger 7. When a plurality of heat exchangers are used, the refrigerant supply box needs to provide larger pressure to ensure smooth flow of the refrigerant, but the load of the refrigerant supply box is large at the moment, and the load of the refrigerant supply box can be reduced by pressurizing through the supercharger.

When a plurality of heat exchangers are used, the refrigerant supply box needs to provide larger pressure to ensure smooth flow of the refrigerant, but the load of the refrigerant supply box is very large at the moment, and the pressure difference value between the refrigerant supply pipe and the refrigerant discharge pipe is increased through the water pumping device to ensure smooth flow of the refrigerant and reduce the load of the refrigerant supply box.
When multiple air-source heat pump machines are installed on the roof of a commercial building, each air-source heat pump machine requires a separate coolant supply tank, which increases costs. As shown in fig. 5, the cooling medium supply pipe 4 of the present invention is connected to the second cooling medium supply pipe 9 of another air source heat pump machine through the series connection, so as to reduce the number of the cooling medium supply boxes and save the cost.
