Abstract

The invention provides a stepless temperature control system, which includes a circulation pump, a hot heat exchanger, a heat medium transmission pipe, a cold heat exchanger, a refrigerant transmission pipe, a proportional regulating valve, an oil supply main pipe, an oil return main pipe and a temperature control system. device. The thermal heat exchanger includes a heat medium inlet, a heat medium outlet, a first heat transfer medium inlet and a heat transfer medium first outlet, and the heat transfer medium first inlet is connected to a circulation pump. The cold heat exchanger includes a refrigerant inlet, a refrigerant outlet, a second heat transfer medium inlet and a second heat transfer medium outlet, and the second heat transfer medium inlet is connected to a circulation pump. The two inlet ports of the proportional regulating valve are respectively connected to the first outlet of the heat transfer medium and the second outlet of the heat transfer medium, and the outlet end is connected to one end of the main oil supply pipe. The other end of the oil supply main pipe is connected to the inlet of the temperature-controlled equipment. The oil return main pipe is connected to the outlet of the temperature-controlled equipment and the circulation pump. The temperature control device controls the valve opening of the proportional regulating valve according to the temperature of the temperature-controlled equipment.

Description

technical field [0001] The invention relates to the technical field of temperature control, and in particular to a stepless temperature control system. Background technique [0002] In the human living environment, temperature plays an extremely important role. As an important physical quantity, temperature is one of the most common and important process parameters in the industrial production process. With the continuous development of industry, the temperature control accuracy requirements are becoming more and more stringent, and the required temperature control range is also becoming wider and wider. [0003] In the existing temperature control system, several fixed heat transfer media are commonly used. For example, frozen brine with a heat transfer temperature of -10°C, cooling water with a heat transfer temperature of 30°C, and steam with a heat transfer temperature of 159°C. The temperature of the heat transfer material can only be at several specific fixed values...
