Description

Refrigeration Refrigerant Circulation System {A Cooling System For Refrigeration}

The present invention relates to a refrigeration refrigerant circulation device for circulating cold air is installed in a refrigerator or a refrigerator (hereinafter referred to as "freezer").

More specifically, in the refrigerant circulation pipe in which the condenser, the compressor, and the heat exchanger are connected in series, the first evaporator and the second evaporator are connected in parallel between the output side of the condenser and the input side of the compressor. It is to provide a refrigerating refrigerant circulation device for improved refrigeration to selectively operate the first evaporator and the second evaporator by installing a solenoid valve on each input side of each.

Conventionally, a refrigerant circulation device in which a pair of evaporators are installed in series in a refrigerant circulation tube in which a condenser, a compressor, and a heat exchanger are connected in series is known, which releases heat to the atmosphere while the high temperature and high pressure refrigerant discharged from the compressor passes through the condenser. It is converted into a liquid refrigerant of medium temperature and high pressure, and reduced in temperature and pressure by passing through a capillary tube to form a liquid state of low temperature and low pressure. The liquid refrigerant passing through the evaporator is sequentially evaporated by absorbing ambient heat. By cooling the surrounding air by the latent heat of evaporation generated as described above, the cooling is performed. The gaseous refrigerant passing through the evaporators connected in series is recovered by a compressor and compressed into high temperature and high pressure repeatedly. Will be implemented.

However, the conventional refrigerant circulator as described above can reduce only the installation cost of the compressor because the compressor is installed alone, but since the divided evaporators are installed in series in the refrigerant circulation tube, the conventional evaporator is installed in series. I couldn't expect anything else.

Therefore, since the evaporator installed in series cannot be operated alone, all evaporators connected in series must be operated according to the amount of food stored in the inside, so refrigerant gas and power are consumed and wasted as in the prior art, thereby reducing operating costs. There was no problem.

The present invention is to provide a refrigerating refrigerant circulation device further improved to solve the above problems.

Another object of the present invention is to install a first evaporator and a second evaporator equipped with a solenoid valve in one compressor in parallel, thereby reducing the installation cost of the compressor and the injection amount of refrigerant gas to reduce the installation cost Refrigeration to reduce operating costs by allowing the first evaporator and the second evaporator to be operated at the same time or selectively by one evaporator depending on the quantity and location of the contents (loaded) in the freezer (or refrigerator) To provide a refrigerant circulation device for.

The first evaporator 11 was supplied with a refrigerant to be operated continuously.

Hereinafter, the operation relationship will be described with reference to the accompanying drawings.

As illustrated in FIG. 1, the refrigerant circulation device 1 in which the solenoid valves 13 and 14 are respectively installed in the first distribution refrigerant circulation tube 15 and the second distribution refrigerant circulation tube 16 is as follows. It works.

While the high temperature and high pressure refrigerant discharged from the compressor (3) passes through the condenser (2), the heat is released to the atmosphere and converted into a medium temperature and high pressure liquid refrigerant. If the solenoid valve 13, 14 provided in each of the first distribution refrigerant circulation tube 15 and the second distribution refrigerant circulation tube 16 is operated (opened). After passing through the capillary tube (5) is reduced in temperature and reduced to a low-temperature low-pressure liquid state is passed through the first evaporator 11 and the second evaporator 12, respectively, the first evaporator 11 and the second evaporator 12 The liquid refrigerant passing through each) is evaporated by absorbing the surrounding heat, thereby cooling the surrounding air by the latent heat generated by evaporation, thereby performing a cooling action, and the first evaporator 11 and the second evaporator. The gaseous refrigerant having passed through (12), respectively, is recovered by the compressor (3). A compression cycle which is in the high-temperature high-pressure air is carried out repeatedly.

Particularly, only the solenoid valve 13 or the solenoid valve 13 is selectively operated among the solenoid valves 13 and 14 installed at the front end of the first distribution refrigerant circulation tube 15 and the second distribution refrigerant circulation tube 16. By selectively passing the gaseous refrigerant to the first evaporator (11) or the second evaporator (12) to selectively perform the cooling action to cool the surrounding air by the latent heat of evaporation that the liquid refrigerant absorbs the surrounding heat evaporated It becomes possible.

As illustrated in FIG. 2A, the refrigerant circulation device 1-1 in which the solenoid valve 13 is installed only in the first distribution refrigerant circulation pipe 15 is operated as follows.

While the high temperature and high pressure refrigerant discharged from the compressor (3) passes through the condenser (2), the heat is released to the atmosphere and converted into a medium temperature and high pressure liquid refrigerant. When the solenoid valve 13 installed at the tip of the first distribution refrigerant circulation tube 15 is operated (opened), the liquid refrigerant supplied from the condenser 2 is supplied to the tube 16. After passing through the capillary tube (5) to reduce the temperature is reduced to a low-temperature low-pressure liquid state is passed through the first evaporator 11 and the second evaporator 12, respectively, the first evaporator 11 and the second evaporator 12 The liquid refrigerant passing through each is evaporated by absorbing the surrounding heat, thereby cooling the surrounding air by the latent heat of evaporation generated as described above, thereby performing a cooling operation, and the first evaporator 11 and the second evaporator ( The gaseous refrigerant that passed through 12) The cycle of being recovered to the presser 3 and compressed to high temperature and high pressure is repeatedly performed.

On the other hand, when the solenoid valve 13 is not operated (closed), it is not supplied to the first evaporator 12. Therefore, since the solenoid valve is not installed, the liquid refrigerant supplied from the condenser 2 is removed. While supplying only to the two-distribution refrigerant circulation tube 16, the liquid crystal passes through the capillary tube 5 and is decompressed under reduced temperature to become a low-temperature, low-pressure liquid state, and passes through the second evaporator 12. The liquid phase passes through the second evaporator 12. The refrigerant is evaporated by absorbing the surrounding heat, thereby cooling the surrounding air by the latent heat of evaporation generated as described above, and the gaseous refrigerant passing through the second evaporator 12 is the compressor (3). It is to be repeated to the cycle that is recovered to be compressed to high temperature and high pressure.

As illustrated in FIG. 2B, the refrigerant circulation device 1-2 having the solenoid valve 14 installed only in the second distribution refrigerant circulation tube 16 operates as follows.

While the high temperature and high pressure refrigerant discharged from the compressor (3) passes through the condenser (2), the heat is released to the atmosphere and converted into a medium temperature and high pressure liquid refrigerant. The liquid refrigerant supplied from the condenser (2) is distributed to the tube (16) and supplied when the solenoid valve (14) installed at the tip of the second distribution refrigerant circulation tube (16) is operated (opened). After passing through the capillary tube (5) to reduce the temperature is reduced to a low-temperature low-pressure liquid state is passed through the first evaporator 11 and the second evaporator 12, respectively, the first evaporator 11 and the second evaporator 12 The liquid refrigerant passing through each is evaporated by absorbing the surrounding heat, thereby cooling the surrounding air by the latent heat of evaporation generated as described above, thereby performing a cooling operation, and the first evaporator 11 and the second evaporator ( The gaseous refrigerant that passed through 12) The cycle of being recovered to the presser 3 and compressed to high temperature and high pressure is repeatedly performed.

On the other hand, when the solenoid valve 14 is not operated (closed), it is not supplied to the first evaporator 12. Since the solenoid valve is not installed, the liquid refrigerant supplied from the condenser 2 is The liquid is passed through the first evaporator 11 through the first evaporator 11 as it is supplied only to the 1-distribution refrigerant circulation tube 15 and passed through the capillary tube 5 to reduce the temperature under reduced pressure and become a liquid state of low temperature and low pressure. The refrigerant is evaporated by absorbing the surrounding heat, thereby cooling the surrounding air by the latent heat of evaporation generated as described above, and the gaseous refrigerant passing through the first evaporator 11 is the compressor (3). It is to be repeated to the cycle that is recovered to be compressed to high temperature and high pressure.

As illustrated in FIG. 2A and FIG. 2B, solenoid valves are installed at one side of the evaporators installed in parallel to operate solenoid valves not provided with solenoid valves, or solenoid valves connected in parallel to operate solenoid valves. Since it can be operated at the same time, when applied to the freezer to operate the freezer as a whole or to selectively operate only a part of the freezer containing the contents can reduce the operating costs.
