Abstract

The invention provides a stepless temperature control system. The stepless temperature control system comprises a circulating pump, a thermal state heat exchanger, a heating medium delivering tube, a cold state heat exchanger, a refrigerant delivering tube, a proportioning valve, an oil supply main tube, an oil return main tube and a temperature controlling device. The thermal state heat exchanger comprises a heating medium inlet, a heating medium outlet, a heat-transfer medium first inlet and a heat-transfer medium first outlet, and the heat-transfer medium first inlet is connected with the circulating pump. The cold state heat exchanger comprises a refrigerant inlet, a refrigerant outlet, a heat-transfer medium second inlet and a heat-transfer medium second outlet, and the heat-transfer medium second inlet is connected with the circulating pump. Two inlet ends of the proportioning valve are connected with the heat-transfer medium first outlet and the heat-transfer medium second outlet respectively, and an outlet end of the proportioning valve is connected with one end of the oil supply main tube. The other end of the oil supply main tube is connected with an inlet of a temperature controlled device. The oil return main tube is connected with an outlet of the temperature controlled device and the circulating pump. The temperature controlling device controls the valve opening degree of the proportioning valve according to the temperature of the temperature controlled device.

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...
