Description of the Invention: [Technical Field] The present invention relates to a water-cooling tester, and more particularly to a water-cooling tester using an environmentally friendly refrigerant, combined with a load, and an external load. [Prior Art] In order to comply with the global environmental awareness, since the end of December 1995, traditional fluorine-carbon carbon (CFCs) refrigerants have been completely eliminated, and the currently widely used hydrochlorofluorocarbon (HCFCs) refrigerants are still With a small amount of ozone depletion potential (ODP) and global warming potentials (GWP), it is about to be shut down in the Montreal Convention, resulting in the current use of HCFC22 refrigerant. The main central air-conditioning main engine and machine tool cooler are cold; the east air-conditioning system brings a very serious impact, so it is imperative to fully use hydrofluorocarbon (HFCs) new environmentally friendly refrigerant. However, because the new environmentally friendly refrigerant part belongs to the non-azeotropic mixed refrigerant series, it has temperature glide and composition shift in the gas-liquid phase coexistence zone, in the system running performance, system refrigerant Problems such as leakage during the filling or assembly maintenance phase are different from pure refrigerants, which will have a considerable impact on system performance, so the system has re-planning problems. At present, there is still no perfect solution to the problem of the temperature drop caused by non-azeotropic mixed refrigerants by domestic machine tool water cooler manufacturers.

When the electronic bypass valve temperature control mode 731 is selected, the comparator receives the temperature value and compares the preset temperature value with an actual feedback temperature. After the φ is compared, the error (4) is transmitted to the proportional differential integral control. The proportional differential controller 751 receives the error signal and performs operational analysis, and then outputs a current signal to an electronic hot gas bypass valve: _"71, the electronic hot gas bypass valve 771 receives the current signal And enter the control of the opening degree of the electronic hot gas bypass valve 771. The above-mentioned proportional hot gas bypass valve 73〇 or electronic hot gas bypass valve 731 temperature control by - strange temperature subject (four) is to keep the temperature at the preset Range, and the thermostatically controlled system 78 〇 outputs an actual circulating water outlet temperature • ', as shown in step 781. Using a temperature sensing element to sense the actual cycle, the water outlet returns the temperature value and transmits the actual The temperature values are fed back to the comparators 740 and 741, and the temperature signals normally tracked by the tracking are compared with the set temperature values to appropriately control the hot gas bypass, so that the accurate and accurate Temperature test test. The water cooler tester described the refrigeration cycle system 300 and the internal load of 60 ports as the body's ability to test various environmentally friendly refrigerants and greatly reduce the space required for testing.
