There are limitations in the practice of experiments and risks of equipment operation using AC power.

Such existing refrigeration and hip pump laboratory training equipment is a large, built-in device that can only explain the principle of operation, and only basic training by a fixed system is to be possible. If the equipment is not a trained trainee, there is a problem in the experimental practice applying the configuration and principle to the system of refrigeration and heat pump laboratory training equipment.

In addition, even if the training by configuring the refrigeration and heat pump laboratory training device takes a lot of time to configure the system, and because the equipment itself is heavy and large, there is a problem that the trainee can not directly configure the system.

An object of the present invention is to solve the problems of the above-described technology, to allow trainees to directly select a variety of active systems to configure and practice various refrigeration and heat pump laboratory training systems. It is a refrigeration system that can configure the application and automatic control circuits using graphic panels similar to the actual models that fit the configuration system by practicing, experimenting, applying, and automatically controlling the operation. And to provide a heat pump training kit device.

1, the compressor 110 includes a compressor 110, a condenser 120, two evaporators 140 and 160, two expansion valves 130 and 150 connected in parallel, and the like. The principle of operation is configured to repeat the cycle of evaporating the refrigerant compressed at high temperature and high pressure in the compressor 110 and then sending it to the condenser 120 to radiate high temperature heat to the outside of the low temperature.

At this time, each of the expansion valves 130 and 150 rapidly lowers the pressure of the high-pressure refrigerant flowing from the condenser 120.

In contrast to cooling, the condenser 120 acts as an evaporator, and the evaporators 140 and 160 are configured to act as condensers so that the condensed refrigerant is heat-exchanged with hot outside air to cool the target point to be cooled. This is composed.

Meanwhile, the receiver 122 temporarily stores the refrigerant condensed in the condenser 120.

The filter drier 124 filters dust and the like of the condensed refrigerant received from the receiver 122 and absorbs moisture to generate a purer compressed refrigerant.

The site class 126 may be configured at the next stage of the filter drier 124 so that the flow of the refrigerant can be visually seen. Due to the nature of the training kit, the flow of refrigerant can be observed with the naked eye.

The first stop valve 128 controls the amount of compressed refrigerant flowing into the evaporators 140 and 160 connected in parallel, that is, connected in parallel in the condenser 120, or condensed refrigerant flowing from the condenser 120. May be blocked from being sent to the evaporators 140 and 160.

The first division chamber 132 is configured to branch and transfer the condensed refrigerant introduced from the condenser 120 to the two evaporators 140 and 160, respectively.

The first check valve 144 and the second check valve 164 pass only the refrigerant passing through the first evaporator 140 and the second evaporator 160, respectively.

In addition, the refrigerant passing through the first evaporator 140 is controlled by the amount of the refrigerant through the second and third stop valves 142 and 146 or the flow of the refrigerant is blocked by the compressor 110. You can also prevent it from flowing.

Meanwhile, the refrigerant passing through the second evaporator 160 controls the amount of the refrigerant through the fourth and fifth stop valves 162 and 166 or blocks the flow of the refrigerant to the compressor 110. You can also prevent it from flowing.

The second dividing chamber 168 may combine the refrigerant introduced from the evaporators 140 and 160 into one and transmit the combined refrigerant to the compressor 110.

In addition, the refrigerant passing through the second division chamber 168 prevents pulsation from occurring through the liquid separator 172 and allows only gas to be sucked into the compressor. The refrigerant passing through the liquid separator 172 again flows into the compressor 110.

Meanwhile, as shown in the drawing, the refrigerant passing through the compressor may be connected to any one or both of two evaporators 140 and 160 connected in parallel without passing through the condenser 120. This can be controlled by adjusting the respective stop valves 142 and 162, or by connecting or not connecting the pipelines. At this time, the sixth and seventh stop valves 112 and 114 are connected to the front ends of the pipes connected to the evaporators 140 and 160, respectively.
