The circulation pump 20 is electrically connected to the frequency converter 203. The frequency converter 203 is used for controlling the rotating speed of the circulating pump motor so as to adjust the pressure of circulating water.
The drinking trough 30 is arranged in the cowshed and used for providing drinking water with appropriate temperature for the cows in real time.
The plate heat exchanger 40 is used to heat the circulating water in the pipeline 50.
The heat medium inlet and the heat medium outlet of the plate heat exchanger 40 are connected with corresponding interfaces of a heating system, a hot water boiler and a steam boiler. The cold medium inlet and the cold medium outlet of the plate heat exchanger 40 are connected with the pipeline 50 of the circulation system.
The plate heat exchanger 40 is provided with a valve, and the valve is used for adjusting the size of heat exchanged by a heat source to realize the adjustment of the water temperature of circulating water.
When the valve is screwed to be large, the flow velocity of the heat medium in the plate heat exchanger is increased, the heat participating in heat exchange in unit time is increased, the heat exchanging in unit time is increased, and the heat exchanging in unit volume of the circulating water is increased. When the valve is screwed up, the circulating water temperature rises, and when the valve is screwed down, the circulating water temperature falls.
