Abstract

The invention provides a heat-recovery thermostatic bath circulating device. The heat-recovery thermostatic bath circulating device is provided with an output end and an input end which are respectively connected with a user side and is characterized by comprising a cold solution box, a hot solution box, a constant-temperature solution box and a compressor, wherein the cold solution box is provided with a refrigerating coil pipe I and a temperature sensor I; the hot solution box is provided with a heating coil pipe and a temperature sensor II; the constant-temperature solution box is provided with a heating device and a temperature sensor III; the compressor, the heating coil pipe and the refrigerating coil pipe I are sequentially communicated with one another to form a refrigerant circulating loop I; the cold solution box and the hot solution box are communicated with the constant-temperature solution box through a fluid adjusting device I and a fluid adjusting device II, respectively. The heat-recovery thermostatic bath circulating device recovers condensation heat generated in the refrigerating process and utilizes the recovered condensation heat to adjust the temperature of a working solution of the device, so that the integral efficiency of the device can be improved. The invention also provides a constant temperature method of the heat-recovery thermostatic bath circulating device. The constant temperature method can be used for recovering condensation heat and has the advantages that the temperature control precision is high, the solution temperature is uniform, and the control response speed is high.

Description

technical field [0001] The invention relates to the technical field of constant temperature bath circulation equipment, and more specifically, relates to a heat recovery type constant temperature bath circulation equipment. Background technique [0002] With the rapid development of science and technology and the continuous improvement of living conditions, refrigeration and air conditioning technology has been widely used in various industries and departments. In order to ensure that the refrigeration and air-conditioning products have excellent performance, the refrigeration and air-conditioning products must go through a series of strict inspections before leaving the factory to test various parameters of the refrigeration and air-conditioning products to test whether they meet the national standards. At present, electrical performance laboratories (including air-conditioning enthalpy difference laboratories, refrigerator performance laboratories, and heat exchanger perfo...
