Embodiment

[0024] Such as Figure 1-2 As shown, an energy-saving water supply system based on automatic heat exchange includes a chilled water pipeline, a circulating water pipeline, a heat exchanger 3 and a controller 4, and the chilled water pipeline is connected to the circulating water pipeline through the heat exchanger 3, so The chilled water pipeline is provided with a first temperature sensor, a temperature control valve 15 and a first electric valve connected to the controller 4 respectively, and the circulating water pipeline is provided with a second temperature sensor and a first electric valve connected with the controller 4 respectively. Two electric valves;

[0025] The controller 4 collects the temperature information of the first temperature sensor and the second temperature sensor in real time, and controls the opening degree of the first electric valve and the second electric valve in real time to adjust the temperature, and at the same time, the temperature control va...

specific Embodiment

[0035] This embodiment is the APOGEE automatic control system for the new circulating water pump room of the No. 2 Volkswagen Plant, which includes 5 temperature sensors, 3 solenoid valves, 1 temperature control valve, 1 bypass stop valve, and a set of APOGEE monitoring system. The specific control process is:

[0036] In summer, the temperature control valve PI is used to adjust, automatically control the opening of the valve, and accurately control the temperature of the circulating water, and APOGEE is responsible for real-time monitoring of the on-site operating conditions;

[0037] In winter, when the outdoor temperature is lower than 15°C, APOGEE controls the bypass valve and closes the chilled water inlet valve. The circulating water does not go through the heat exchange of the plates, and returns directly to the water for further use.

Abstract

The invention relates to an energy-saving water supply system based on automatic heat exchange, comprising a chilled water line, a circulating water line, a heat exchanger and a controller. The chilled water line is connected with the circulating water line through the heat exchanger. The chilled water line is provided with a first temperature sensor, a temperature control valve and a first electric valve all connected with the controller. The circulating water line is provided with a second temperature sensor and a second electric valve both connected with the controller. The controller acquires temperature information of the first and second temperature sensors in real time and controls openness of the first and second electric valves in real time to adjust the temperature; the temperature control valve automatically controls the openness thereof, thus temperature of circulating water is further precisely controlled. Compared with the prior art, the energy-saving water supply system has the advantages such that labor cost is greatly reduced and work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a water supply system, in particular to an energy-saving water supply system based on automatic heat exchange. Background technique [0002] The process circulating water is used to cool various machines, welding torches and processing processes. The current cooling circulating water mainly has two methods: open cooling tower air cooling, chilled water cooling through the plate, and the circulation The cooling water with high water quality requirements generally adopts the closed cooling method of the board, otherwise, the cooling tower is used for air cooling. When cooling, the flow rate of chilled water, the speed of the fan, etc. are usually controlled by collecting the temperature of the circulating water. These methods can achieve the effect of saving energy and reducing consumption. But it is safe to maximize energy saving and consumption reduction. Contents of the invention [0003] The object of the present inventi...
