Embodiment example

[0029] Below, the embodiment of the present invention is described in detail as follows by accompanying drawing:

[0030] See Figure 1-6 , the present invention does not use fuel oil or daytime electricity, but uses low-cost AC220V power on the ground at night to start the AC refrigerator 1 installed in the front of the refrigerator, refrigerated van truck, low-temperature warehouse, and low-temperature showcase. Connect the cold storage tank 6 that stores the low-temperature latent heat P.C.M phase change material (Phase Change Material) 11, and install the gas heat exchanger 3 and the double-pipe refrigerant distributor 4 in the cold storage tank 6, and pass through the expansion valve 2 in the AC refrigerator 1 The discharged refrigerant gas (Gas) circulates in a direct expansion type, and the low-temperature latent heat P.C.M phase change material in the cold storage tank 6 changes from a liquid phase to a solid state under a certain temperature condition, is frozen and s...

Abstract

A multi-cooling type PCM(Phase-Change Material) thermal storage system is provided to reduce heat loss through unnecessary heat exchange by employing insulating panels and maintain desired temperature of a storage container. A multi-cooling type PCM thermal storage system comprises a brine circulation heat exchange coil(10), an air circulation heat exchange tube(5), a circulating pump(9), and a blower(12). The brine circulation heat exchange coil is connected to the circulating pump and heat-exchanges with a low temperature latent heat PCM(11) stored in a thermal storage tank. The air circulation heat exchange tube heat-exchanges the low temperature latent heat PCM secondly. The circulating pump is installed in the upper part of the storage tank and circulates the brine, which is cooled by heat-exchange with the low temperature latent heat PCM, into the brine circulation heat exchange coil. The blower draws the internal air of the storage container, implements first and second heat-exchange with the brine circulation heat exchange coil and the air circulation heat exchange tube, and discharges the multi-cooled air into the storage container in order to maintain the required temperature.

Description

technical field [0001] The present invention is about the technology of multi-cycle cooling P.C.M cold storage system. Specifically, it is to combine the AC refrigerator driven by low-cost nighttime electricity with the container installed in the refrigerated and frozen van truck, low-temperature warehouse, low-temperature container, etc. The cold storage tank with low-temperature latent heat P.C.M phase change material (Phase Change Material) is connected, and the refrigerant gas (Gas) discharged through the expansion valve of the AC refrigerator circulates in the gas heat exchanger inside the cold storage tank connected to the refrigerator In order to freeze and cool the low-temperature latent heat P.C.M phase change material that starts to freeze at a specified temperature inside the cold storage tank, and install a heat insulation layer to block the heat exchange with the external air of the cold storage tank, in order to maintain an appropriate temperature in the cargo box...
