Description

Hybrid cooling system for large factories and livestock using shrinkage heat tank {LARGE FACTORY USING WATER STORAGE TANK AND HYBRID COOLING APPARATUS FOR CATTLE SHED}

The present invention relates to a cooling device, and in particular, in a state in which cold water is stored by cooling water in a shrinkage tank in a freezer using late-night electricity, the shrinkage tank is controlled according to the indoor temperature and humidity of a large factory, warehouse, and barn during the day. The present invention relates to a hybrid air conditioner for large factories and livestock using a contraction heat bath that supplies cold water to a cooling pad or a cooling coil, or simultaneously supplies a cooling pad and a cooling coil to perform indoor cooling.

In general, large factories, livestock houses, warehouses, etc. have ventilation, steam spraying or ventilation facilities installed to prevent excessive increase in indoor temperature during hot summer months or to prevent contamination of internal air. The inability to sufficiently lower the indoor temperature of the building makes it impossible to operate in large factories, or causes a problem of inferior operation efficiency, damages to goods being stored in warehouses, and livestock due to high temperatures in livestock houses. It leads to a serious situation, such as exhaustion or even the death of livestock in severe cases.

On the other hand, in the case of installing a refrigerant type air conditioner in such a large factory, warehouse, or barn, it is not practical because the burden of excessive facility cost as well as the electricity cost is unbearable, and cooling using geothermal heat or groundwater to reduce operating costs Some devices have been developed and used.

For example, as published in Korean Patent Registration No. 10-1606323, a cooling device using a cooling pad is posted.

In the cooling device using the cooling pad, as shown in FIG. 1, the cooling pad (C) is coupled to a support assembly composed of an upper cover 100, a lower gutter 300, and a side finish (not shown) to That is, it is installed between the upper wall 10 and the lower wall 20. Hangers 200 are arranged and fixed to the ceiling of the inner space of the upper cover 100 of the support assembly at predetermined intervals, and the water supply pipe 42 is inserted into the hanger 200 with an open lower end. In addition, the water supply pipe 42 is connected to the water supply pump 40 through the flow control valve 44 and the drain valve 46 and is connected to the water collecting tank 30.

On the other hand, the water ejected from the water supply pipe 42 flows down from the top of the cooling pad (C) and is collected in the lower gutter 300, and the collected water is collected through a drain pipe D connected to the lower gutter 300. 30).

However, the cooling apparatus using such a cooling pad has a limitation in the capacity of the water collecting tank, the cooling efficiency is lowered because the temperature is increased by continuous circulation, and the internal humidity is increased by the water flowing through the cooling pad.

In order to solve this problem, a building cooling device using a cooling pad, which is Korean Patent No. 10-1528408, has been posted.

The building air conditioner using the cooling pad is constructed in the form of a pad of a predetermined thickness through which water can flow up and down and has ventilation in the front and rear, as shown in FIG. 2, and is installed on one wall surface (W1) of a factory or barn building (B). An exhaust fan 200 provided with a cooling pad 100 to be used, a shutter 210 installed on the other side wall W2 or ceiling of the building B and opened during operation and closed when stopped, and the cooling pad It includes a water supply 300 for supplying water to the 100 and a pre filter 400 installed outside the cooling pad 100 to provide outdoor air by the operation of the exhaust fan 200. Building cooling using a cooling pad that prevents static electricity from being generated and exhibits a deodorizing function by performing heat exchange with water flowing along the cooling pad 100 while flowing into the room through the cooling pad 100 In the device; The cooling pad 100 is coated with paraffin on palm tree fibers, which is a kind of natural pulp, and the water supply 300 is a water reservoir 310, water supply connected from the water reservoir 310 to the top of the cooling pad 100 A line 320, a pump 330 installed in the water supply line 320, a recovery line 340 connected from the lower portion of the cooling pad 100 to the water reservoir 310, the water reservoir 310 A heat exchanger 350 through which a refrigerant is circulated in order to maintain water below a predetermined temperature, and a refrigerator 360 connected to the heat exchanger 350 to cool and supply the refrigerant.

However, the building air conditioner using the cooling pad also only lowers the temperature of water using a refrigerator, but there is a problem in that the internal humidity increases due to water flowing through the cooling pad.
