Description

Technical Field

[0001] The invention relates to the technical field of energy refrigeration, and in particular to a system that can efficiently store cold through water. Background Art

[0002] At present, due to the shortage of electricity during peak hours, and the inability to fully utilize electricity during non-peak hours, a time-of-use electricity price policy is generally adopted to alleviate the shortage of peak electricity. The purpose is to improve the utilization rate of electricity during non-peak hours. Some technical solutions disclose a system that can store cold by turning water into ice. The system uses the low electricity price period at night to store water into ice, and melts the ice to release the stored cold during the high electricity price period. During the peak electricity price period, electricity is basically not used, which reduces the power load of the water storage cooling system during the peak period of the power grid. The current water storage cooling system has an insulated water tank structure. The existing insulated water tank structure mainly has three layers: an outer shell, an insulation layer, and a water tank liner. Such insulation means are usually polyurethane foam, which has poor thermal conductivity. This property is used to block the heat from being transferred from the inner tank to the outer shell. In fact, the foam insulation layer cannot block the heat from radiating outward through the inner tank itself, nor can it reflect the radiated heat back, which causes the heat to be continuously lost. In summary, the current three-layer structure of the thermal insulation water tank has a poor single-layer insulation means, which is also easy to cause heat waste. Summary of the invention

[0003] In response to the above problems, we have developed a system that can efficiently store cold water. This system can make up for the above defects. The key point is to inhibit the conduction and radiation of heat from the inner tank of its efficient thermal insulation water tank itself, which can effectively reduce the heat loss of the heat source.

[0004] In order to achieve the above-mentioned invention content, the present invention adopts the following technical scheme: it includes two water circulation pipes consisting of a refrigeration main unit, an insulated water tank and two pipes, namely, No. 1 water circulation consisting of pipe No. 1 and a high-efficiency insulated water tank and No. 2 water circulation consisting of a fan coil unit, pipe No. 2 and a high-efficiency insulated water tank. The high-efficiency insulated water tank includes an outer shell, an efficient insulation layer and an inner tank, which are the outer shell, the high-efficiency insulation layer and the water tank inner tank from the inside to the outside respectively. The outer surface of the water tank inner tank is coated with a ceramic hollow microparticle coating water tank inner tank insulation layer, the inner surface of the outer shell is coated with a ceramic hollow microparticle coating outer shell insulation layer, the ceramic hollow microparticle coating water tank inner tank insulation layer is coated with a soft metal reflective layer composed of single-sided metal aluminum foil reflective paper, and the reflective surface of the soft metal aluminum foil reflective paper faces the water tank inner tank, which can effectively prevent the heat loss of hot water.

[0005] Furthermore, the fan coil unit includes multiple coils, the fan coil unit includes multiple fan coils, a water collector and a water distributor are installed on the No. 2 pipeline, a plurality of No. 2 connectors are designed on the water collector, and a plurality of No. 1 connectors are designed on the water distributor, and each No. 2 connector and No. 1 connector are respectively connected to the two ends of a coil.

[0006] Furthermore, the water distributor and the water collector are connected through a pipeline, and a bypass valve is provided between the water distributor and the water collector.

[0007] Furthermore, the No. 1 pipeline is composed of a No. 1 water inlet pipe and a No. 1 drain pipe. The water from the No. 1 drain pipe comes from the water in the high-efficiency thermal insulation water tank, and then the water from the No. 1 drain pipe enters the refrigeration main unit. The water in the refrigeration main unit is transported into the high-efficiency thermal insulation water tank from the No. 1 water inlet pipe, and the No. 1 water pump is installed on the No. 1 drain pipe.

[0008] Furthermore, the No. 2 pipeline is composed of a No. 2 water inlet pipe and a No. 2 drainage pipe. The water in the No. 2 drainage pipe comes from the high-efficiency thermal insulation water tank, and then enters the fan coil unit through the No. 2 drainage pipe. The water in the fan coil unit is transported back to the high-efficiency thermal insulation water tank through the No. 2 water inlet pipe. The No. 2 water inlet pipe and the No. 2 drainage pipe are both connected to a pipeline.

[0009] In one or more implementation cases, the high-efficiency thermal insulation water tank is designed with a water supply pipe, and a water supply valve is installed on the water supply pipe.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: by adopting the technical solution of the present invention, the high-efficiency water storage cooling system of the present invention contains a high-efficiency heat-insulating water tank that can reduce heat loss. After the heat-insulating layer of the inner liner of the ceramic hollow microparticle coating water tank is painted and dried to form a film, a plurality of spherical vacuum cavity layers composed of hollow ceramic particles will be formed in the hollow ceramic, and the cavity layer will form a plurality of high-efficiency heat-insulating layers. At the same time, the heat reflection efficiency of the surface of the heat-insulating coating is above 85%. When the radiated heat is incident on the surface of the heat-insulating coating, the surface of the heat-insulating coating will reflect more than 84% of the heat. The heat is reflected back, and the thermal insulation coating itself can absorb 10%-20% of the heat; the metal aluminum foil reflective paper laid on the surface of the thermal insulation layer of the water tank inner liner can reflect the heat emitted from the thermal insulation layer of the water tank inner liner, and the reflected heat is reflected back into the water tank inner liner again, thus avoiding the heat from penetrating the polyurethane insulation layer and being wasted, and further preventing the heat from being lost from the water tank inner liner; the thermal insulation layer of the coating shell formed by the ceramic hollow microparticles painted on the inner surface of the shell can reflect back more than 85% of the heat radiated from the water tank inner liner, thereby keeping the heat in the water tank with maximum efficiency.
