Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The hydraulic module is used for exchanging heat between the refrigerant in the refrigerant flow channel and the water in the water delivery flow channel so as to heat the water or cool the water, so that the water with the set temperature is output and is delivered to a water storage device such as a water tank or a heat release device such as a ground heating pipe and a radiator.

The inventor finds that the heat exchange device, the small water tank heater, the water pump, the expansion tank, the temperature controller, the electric control box and other parts of the hydraulic module are improperly designed in the arrangement positions in the box body, so that moisture is easy to remain in the inner space of the parts, and the residual moisture is easy to corrode the inner structure of the parts. For example, when the hydraulic module is checked out, the water in the hydraulic module is discharged, and if the water remains, the hydraulic module is put into the home of the user for a long time, and the water remains easily to corrode the inside of the parts. Therefore, it is necessary to set the arrangement positions of the components inside the hydraulic module so that the water in the internal space of the hydraulic module components can be more sufficiently discharged. Based on the above, the embodiment of the application provides a hydraulic module and a heat pump system.

The hydraulic module provided by the embodiment of the application can be used for an air energy water heater, and also can be used for household heating equipment such as floor heating, radiators and the like, and is not particularly limited.

The application does not limit the number of connecting pipelines for connecting two functional devices, and can be specifically selected according to actual requirements.

Optionally, one of the connection pipelines of the integrated pipe subsystem is a transition pipe 610, the transition pipe 610 communicates with the first water outlet 320a and the second water inlet 410a, specifically, one end of the transition pipe 610 is connected to the first water outlet 320 to communicate with the water delivery channel, and one end of the transition pipe 610 is connected to the second water inlet 410 to communicate with the water storage cavity.

The third straight pipe 623 extends from the second straight pipe 622 in a direction forming an angle with the second straight line B to be connected to the water drawing end 510 of the water pump 500.
