Description of the invention: [Technical field to which the invention belongs] 匕 The invention relates to a kind of cold; the energy-saving temperature control device of the transformer of the east device, and the combination of the inverter compressor and the hot gas bypass circuit and the temperature/ Dish control 'at the low negative scale at the same time to reach the capacity (four) m precision temperature control function. [Prior Art] The cold device is used to cause the device to generate a high temperature, such as a machine tool or a semi-guided process, which causes the thermal displacement to deviate from the center position accuracy. Therefore, in order to cooperate with the production case, the party-last name ~ 7 Xia and then affect the processing of the cold, and then suppress the high temperature, the need to properly adopt the process of high value-added products. <Precision' can produce high-quality, the above-mentioned money-making preparation towel, the function of the health control parameter, the traditional setting = the self-demanding precision, the dish application frequency control technology to achieve this requirement, The green energy demand, the processing effect of the gluten moon, and the trend of the traditional cold material J cheng into the future process refrigerator. And the need for evaporator, machine, condenser, expansion device, gold cooling, etc., in the traditional low-end refrigeration device, often with a fixed-frequency compressor with expansion resistance ~ white cold / fruit device A π load flow , will make i shrink machine volume and temperature control 'in low shrink machine usually need to delay pressure 'pressure; after the machine stops to protect the pressure caused by temperature (four) so = fine mode ~ so the temperature characteristic curve is jagged (such as 201022602 Figure 2), does not really achieve the thermostat control function. 'The traditional freezer also has a fixed-frequency compressor, with hot gas bypassing the way to carry out flow and temperature control. When the load is low, the compressor still does not stop, but due to the unloading consideration, a large number of high-temperature compressors are exported. The high-heat gaseous refrigerant is directly added to the front end of the evaporator at the rear end of the expansion device, which also causes unstable temperature control and high temperature. In conventional high-end refrigeration units, flow control and temperature control are also performed using an inverter compressor in conjunction with an expansion device. Such a system has the advantages of energy-saving operation, excellent flow rate, and temperature control when stabilizing the load. However, when operating under low load conditions, if the flow rate range is lower than that of the inverter compressor, the compressor may still stop at this time. As with the disadvantage of 0N/0FF type, the temperature control will be unstable. In the traditional high-end refrigerating device, the flow rate and temperature control are also performed by using an inverter compressor, an expansion device and a bypass circuit device (the system is shown in Fig. 3). Such a system also has energy-saving operation under stable load, and excellent flow rate. And the advantages of temperature control. However, when operating under low load conditions, if the flow rate range is lower than the inverter compressor, the hot gas bypass valve will open to adjust the flow rate so that the large amount of hot refrigerant gas for the purpose of unloading is directly injected. The evaporator causes a disturbance in the temperature, making the temperature control unstable. In addition, if the expansion device is opened correspondingly, and more refrigerant is passed to control the temperature, the inverter compressor will operate at a higher rotation speed (frequency) when the load is low, which is a waste of energy. The present invention can improve the above-described deficiencies in the construction of an inverter compressor. SUMMARY OF THE INVENTION 201022602 In order to solve the above-mentioned shortcomings of the prior art, the present invention is a variable frequency energy-saving temperature control device for a refrigeration device, the main purpose of which is to cooperate with a first bypass circuit and a flow control valve thereof with an inverter compressor. The two bypass circuits and their flow control valves respectively control the flow rate and temperature, which can solve the temperature disturbance caused by the unstable temperature control caused by the compressor stop at low load and the opening of the hot gas bypass valve for the purpose of unloading when the low load capacity is eliminated. In addition to energy-saving effects, it also has a fast temperature-controlled reaction and constant temperature control, which simultaneously achieves flow control and precise temperature control at low loads. In order to achieve the above object, the present invention is a variable frequency energy-saving temperature control device for a refrigeration device, which comprises an inverter compressor, a condenser, an expansion device, a steaming device, and the variable frequency energy-saving temperature control device further comprises: The bypass circuit and the flow control valve receive the high-temperature and high-pressure gaseous refrigerant outputted by the inverter compressor, and output to the wheel-in end of the evaporator, as a heat source for temperature control; the j-th pass circuit and the flow control (4), receive the change The gas refrigerant that is output by the pressure reduction machine is output to the input end of the change! use. The first flow control valve and the second flow control valve are used to quickly react and evaporate the working temperature fluctuations of the working machine, and the low phenomenon, Performing accurate temperature control and control (4) Unstable steps on the fortune of the money (4), is illustrated by the following figure and the detailed description of the invention, and the company does not help. 201022602 The embodiments of the present invention will be described in detail in conjunction with the following drawings. As shown in FIG. 1 , it is an implementation form of the variable frequency energy-saving temperature control device of the refrigeration device of the present invention, which comprises: an inverter compressor, having the function of frequency conversion adjusting power, and the variable pressure compressor 1 The refrigerant at the input end 11 is compressed into a high temperature and high pressure gaseous refrigerant; a condenser 2 receives the high temperature and high pressure gaseous refrigerant at the output end 12 of the inverter compressor 1, and after being cooled by the condenser 2, a high pressure liquid is output from the output terminal 22. a refrigerant; an expansion device 3 receives the high-pressure liquid refrigerant outputted from the condenser 2, and outputs a low-pressure liquid helium refrigerant through expansion operation; a first bypass circuit 8 and a flow control valve 4 thereon, and an inverter compressor 1 output The high temperature and high pressure gaseous refrigerant outputted from the terminal 12 is connected to the first input end 61 of an evaporator 6, the control valve 4 can control the flow rate of the refrigerant; the second bypass circuit 9 and the flow control valve 5 thereon, the frequency conversion The high temperature and high pressure gaseous refrigerant outputted from the output end 12 of the compressor 1 is connected to the input end 11 of the inverter compressor 1; an evaporator 6, the second input end 63 and the second output end 64 of the evaporator 6 and a Working machine 7 The working fluid is connected, and the working system refers to one of pure water, brine and cooling oil, and the evaporator 6 is used to exchange heat of the two input Φ ends (61, 63). The working principle of the invention is that the output end of the inverter compressor 1 is connected to the output end of the expansion device 3, and the temperature control hot gas bypass circuit 8 between the input end of the evaporator 6 is used as the load is drastically changed or low (zero). Temporarily supplement the heat source during the load, so that the expansion device does not need to be drastically changed, which affects the temperature control accuracy. The output end of the inverter compressor 1 is connected to the first output end 62 of the evaporator 6, and the hot gas bypass circuit 9 for unloading before the input end 11 of the inverter compressor 1 is used for unloading, so that the inverter compressor is not low in load. Stop at the most operating low frequency load, unload a larger amount of gaseous hot refrigerant without flowing through the evaporator, avoiding the temperature control of 201022602 disturbing working fluid. The refrigerant is compressed by the inverter compressor 1 into a high-temperature and high-pressure gas bear. The condenser 2 dissipates heat into a high-pressure liquid refrigerant, flows through the swelling refrigerant, and the low-pressure liquid refrigerant flows through the evaporator 6 to absorb the working fluid. The heat generated 're-enters the inverter compressor i, and becomes a mechanical expansion device 3, which can control the flow rate of the liquid refrigerant and determine the method.

In the case of a drastic load, the first flow control valve (4) is opened, and the hot gas bypass circuit 8 allows an appropriate amount of high-temperature gaseous refrigerant to be directly added from the first input end 61 of the evaporator 6, temporarily supplementing the original Load the heat source, then slowly close the hot gas bypass valve 4 and close the opening of the small expansion device, and finally return to the temperature control state directly by the expansion device. Thanks to the cooling source (liquid refrigerant) and the supplementary heat source (Southern temperature gaseous refrigerant), it is possible to quickly react to the situation where the evaporator 6 load drops drastically. If the load is lower than the load running at the lowest frequency of the inverter compressor, the second flow control valve 5 (the second hot gas bypass circuit is opened) to maintain the lowest frequency of the inverter compressor for continuous operation to achieve energy saving effect. When the load rises sharply (ie, when the working machine 7 is in a high load state) 'The first and second flow control valves (4, 5) remain closed 'the expansion device 3 is increased in opening' to allow an appropriate amount of liquid refrigerant to flow into the evaporator In this way, the situation in which the load of the evaporator 6 is drastically increased can be quickly reacted, and the strange temperature can be accurately controlled. When the load is reduced beyond the unloading amount of the inverter compressor (that is, when the working machine 7 is in a low load or no negative cutting state), the inverter compressor 1 can maintain the 201022602 operation at the lowest speed (flow rate), and at this time, the second flow control valve 5 Open, let the excess refrigerant not flow through the condenser 2, expansion device 3, evaporator 6, directly flow back • The short-circuit of the suction end of the inverter compressor 1 can make the inverter compressor 1 stop, and also because of unloading A large amount of high-temperature gaseous refrigerant does not flow through the evaporator 6, so that temperature control is not affected and the constant temperature state can be maintained. It does not affect the temperature control of the evaporator, nor does it cause the opening of the expansion device to increase. When there is no low load, the inverter compressor runs at high speed (high frequency), which wastes energy. According to the disclosure of FIG. 1 above, it can be understood that the present invention mainly performs temperature and flow control respectively with a first flow control valve and a second flow control valve, in addition to energy saving effects, The utility model has the advantages of rapid temperature control reaction, constant temperature control, and simultaneous flow control and precise temperature control at low load. In the field of industrial process equipment, it has extremely high efficiency, so patent applications are filed to seek patent protection.
