Abstract

In the conventional refrigeration system of agricultural cold storage system, the compressor (1) and the condenser (2) is located outdoors, the expansion valve (3) and the evaporator (4) is located in the room, the refrigerant piping is long, which is a factor that reduces the refrigeration efficiency, Energy consumption is high because the refrigeration cycle is fully operational in winter.

In addition, the construction period was long due to the necessity of facility construction, and it was one of the factors that increased the construction cost.

The present invention has been made to devise an integrated freezer for agricultural cold storage to improve these problems.

In order to solve the above problems,

First, the compressor (1), the compression means, the condensation coil (5), the expansion valve (3), the evaporation coil (7) as the evaporation means by sequentially connecting the refrigerant pipes in one case (17) To make an integrated refrigerator.

Therefore, the length of the refrigerant pipe is shortened, the refrigeration efficiency is increased, and the equipment construction is unnecessary, so the effect of shortening the air and the construction cost are reduced.

Second, by installing a damper incorporating an air conditioning method in the integrated freezer for agricultural products cold storage, energy saving effect is greatly increased as a natural freezing system using winter air.

Natural outdoor effect can be expected by stopping the operation of the refrigeration cycle when the outside air temperature is below a certain temperature through the outdoor sensor 14 and introducing the outdoor air into the room,

When the outside temperature is above a certain temperature, the proper indoor temperature is maintained by the operation of the refrigeration cycle, and when the evaporation coil 7 is defrosted, the outside air is introduced to allow natural defrosting.

Therefore, significant energy savings can be expected.

2 is a refrigeration system for low temperature storage of agricultural products of the present invention. The refrigeration cycle apparatus of the present invention for the purpose of the compressor (1) and the compressor (1) for sucking the refrigerant of low pressure to compress the refrigerant gas of high pressure The condensing coil 5 for condensing the discharged refrigerant gas by heat exchange is connected to the refrigerant pipe, and the expansion valve 3 for reducing the high pressure refrigerant from the condensing coil 5 and the condensing coil 5 are refrigerant pipes. The evaporation coil 7 for evaporating the low pressure refrigerant from the expansion valve 3 and the expansion valve 3 through a refrigerant pipe, and suck the low pressure refrigerant from the evaporation coil 7. By connecting the compressor (1) and the evaporating coil (7) which is compressed to a high-pressure refrigerant gas by a refrigerant pipe, as shown in Figure 2 constitutes all the refrigeration cycle in the case (17). ) At the bottom of the case (17) Kimyeo, it positions the condensation coil (5) on its top. The condensation fan (6) is installed in front of the condensation coil (5) to increase the condensation efficiency. Position the expansion valve (3) between the condensation coil (5) and the refrigerant pipe connecting the evaporation coil (7), the evaporation coil (7) is located above the expansion valve (3). The upper and lower sides of the case 17 are separated by a wide plate between the expansion valve 3 and the evaporation coil 7 to prevent the flow of air to each other, and only a refrigerant pipe passes through the hole. A water tank 15 is installed below the evaporation coil 7 to collect condensation water generated during heat exchange of air passing through the evaporation coil 7 and discharged out of the case 17 through the drain hose 16. 홴 (8) is located on the upper part of the 7), the duct is installed in two directions on the upper part of the 홴 (8), one direction is connected to the room, and the damper 10 is installed at the inlet, the other direction Is installed in the outside air and the damper 11 is installed at its inlet. The duct is installed in two directions on the front of the evaporation coil 7 as shown in FIG. 2 and the one direction is connected to the room, and the damper 12 is connected to the inlet. The other direction is connected to the outside air and a damper (9) is installed at its inlet. The dampers 9, 10, 11, and 12 have a structure capable of opening and closing. For the operation of the design, an outdoor sensor 14 capable of sensing outside temperature is installed in the case 17. To install the indoor sensor 13 that can sense the indoor temperature in the room. When explaining the operation according to the present invention configured as described above, first, the outdoor air to obtain a natural freezing effect by introducing the indoor air of a certain temperature or less. Can be. In other words,

Usually produce is harvested in autumn and stored at room temperature + 5 ℃ until spring. In other words, the operating rate of agricultural cold storage is quite high in winter.

On the other hand, Table 1 shows that the average outside temperature in winter (December to February) is kept below a certain temperature.

<Excerpt from the Meteorological Agency's Internet site archive

It was designed by taking into consideration that when the outdoor sensor 14 is detected in the winter, the cooling cycle is stopped and the damper 12 is closed, and the damper 12 is closed, and the damper 12 is operated to inhale cold air through the damper 9. In addition, the damper 10 is opened to flow into the room while the damper 11 is closed. At this time, when a certain temperature is detected when the indoor sensor 13 is detected, the damper 9 and the damper 10 are closed and the operation of the shock absorber 8 is stopped. When the indoor sensor 13 is detected again when the temperature is above a certain temperature, the cycle is repeated again. In this way, natural cooling is possible when the temperature is below a certain temperature, and energy saving effect is large because there is no operation of the refrigeration cycle. When the temperature is above a certain temperature, operate the refrigeration cycle to close the damper (9), operate the fan (8) while the damper (12) is opened, suck the indoor air, pass the evaporation coil (7), and heat exchange at this time. The air is cooled to close the damper (11), open the damper (10) to enter the room to maintain the room temperature properly. At this time, the condensation water generated when the indoor air passes through the cold evaporation coil is collected in the bucket 15 and discharged out of the case 17 through the drain hose 16. This cycle requires defrosting due to the dropping of the evaporating coil (7). In this case, the damper (12) is closed and the damper (9) is opened to operate the fan (8) to inhale outside air above a certain temperature to evaporate the coil (7). And the damper 10 is closed, the damper 11 is opened and the damper 11 is opened and discharged to the outside. This cycle enables natural defrosting. Refrigerator refers to the existing cold storage system for agricultural products, compressors, condensers, expansion valves, and evaporators should arrive at the site and refrigerate piping work, and refill the refrigerant. In the case (17) of the compressor (1) and the condensation coil (5), the expansion valve (3), the evaporation coil (7), the evaporation means of the condensation means by interconnecting the refrigerant pipe and filling the refrigerant integrally Composed phase The means, so integral to arrive on the scene it can be operated only when the electrical equipment construction without the necessary supplies.

The present invention as described above, the refrigerant piping is shortened by the integration of the refrigerating device, the refrigeration efficiency is increased, the equipment construction is unnecessary, the air shortening, the price can be reduced effect, compared to the full operation of the winter freezer in the cold storage of agricultural products Significant energy savings can be achieved.

In addition, there is an advantage that the trial and error that comes from the knowledge of the farmers can fully cope in advance with the standardization of the refrigeration apparatus.
