A constant temperature control method for automatic temperature control heating water circulation

Abstract

The invention discloses an automatic temperature control heating water circulation constant temperature control method. The automatic temperature control heating water circulation constant temperature control method uses an automatic temperature control heating water circulation constant temperature heat source experiment device which is composed of a heating water tank, a temperature and water circulation control device and a constant temperature hot water tank, wherein the heating water tank is divided into a first water tank and a second water tank, the first water tank and the second water tank are communicated through a connection pipe on a heat insulation organic glass plate, four holes are formed in the side wall of the heating water tank, a water adding pipe, a water outlet pipe, a water return pipe and a cable pipe are respectively installed in the four holes, the temperature and water circulation control device is composed of a power source switch, an outage protector, a temperature controller, a relay, a water circulation pump switch and an automatic water adding controller, and a water inlet pipe and a water outlet pipe are arranged at the top of the constant temperature hot water tank in butt fusion mode, and respectively connected with the water outlet pipe and the water return pipe of the heating water tank. The automatic temperature control heating water circulation constant temperature heat source experiment device is used to achieve automatic temperature control heating water circulation constant temperature control. The automatic temperature control heating water circulation constant temperature control method saves energy, and is safe, convenient to operate, high in temperature control accuracy, and wide in application range.

Description
