Novel cold accumulation system for phase-change cold accumulation air-conditioning machine room

Abstract

The invention discloses a novel cold accumulation system for a phase change cold accumulation air conditioner machine room, and belongs to the technical field of cold accumulation systems. The novel cold accumulation system for the phase change cold accumulation air conditioner machine room comprises a barrel, wherein T-shaped rods which are symmetrically distributed are fixedly connected to the inner side wall of the barrel; a hollow mounting column is fixedly connected to an inner cavity of the barrel through the T-shaped rods; a transmission rod is rotatably connected to an inner cavity ofthe hollow mounting column; an intermittent water inlet mechanism is connected to the top end of the transmission rod; a flow equalizing mechanism is connected to a water inlet of the barrel; a drivengear is fixedly connected to one end, penetrating through the bottom of the barrel, of the transmission rod; an intermittent reciprocating transmission mechanism matched with the driven gear is further arranged at the bottom of the barrel; a transmission mechanism is fixedly connected to the middle of the hollow mounting column; and cold accumulation plates are fixedly connected to the transmission end of the transmission mechanism and evenly surround the periphery of the hollow mounting column. According to the cold accumulation system, a secondary refrigerant or a water gap makes full and uniform contact with the front faces and the back faces of the cold accumulation plates, and then the uniformity of the temperature in a water tank is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cold storage systems, in particular to a cold storage system for a novel phase change cold storage air conditioner room. Background technique [0002] With the popularity of air-conditioning, the proportion of electricity consumed by air-conditioning in building energy consumption is gradually increasing. In summer, the energy consumption of air-conditioning accounts for 85% of building energy consumption, which makes the peak-to-valley difference in electricity use larger, and there is a phenomenon that electricity demand exceeds supply during peak periods of electricity consumption, and excess electricity consumption occurs during low-peak periods of electricity consumption. Moreover, because the country has introduced a power policy that encourages peak shifting and valley filling to make full use of power resources, cold storage air conditioners are therefore favored by people. [0003] The so-called...

Problems solved by technology

[0004] The phase change cold storage water tank using phase change material as the cold storage medium has the advantages of large energy storage per unit volume and high cold storage density. The brine or water in the water tank is fully and evenly contacted with the phase change material in the water tank to perform comprehensive and efficient heat exchange. In the prior art, the brine or water entering the water tank is often directly through a pipe. The flow rate of the input into the water tank is large and concentrated, and the brine or water flows out quickly after flowing into the water tank, resulting in the inability of the brine or water to fully and evenly contact with the phase change material, which will easily lead to a decrease in the internal temperature of the water tank. Inhomogeneous, the heat exchange rate of the phase change material cannot meet the actual requirements, which ultimately affects the cold storage and cooling effect of the water tank
