Water distribution device of water cold accumulation system

Abstract

The invention relates to a water distribution device of a water cold accumulation system. The device comprises a cold accumulation tank, a first water distributor and a second water distributor, wherein the first water distributor and the second water distributor are respectively positioned at the top and the bottom of the cold accumulation tank; the first water distributor comprises a first water separation disc, a high-temperature water access pipe communicated with the first water separation disc, and first water distribution pipes; multiple first water distribution pipes are uniformly distributed around the first water separation disc in the peripheral direction, and are all provided with first scattering holes with upward openings; the second water distributor comprises a second water separation disc, a low-temperature water access pipe communicated with the second water separation disc, and second water distribution pipes; and multiple second water distribution pipes are uniformly distributed around the second water separation disc in the peripheral direction, and are all provided with second scattering holes with downward openings. In cold accumulation, cold water uniformly and stably flows into a low-temperature layer from the second scattering holes; and in cold release, hot water uniformly and stably flows into a high-temperature layer from the first scattering holes. The openings of the first scattering holes are upwards, and the openings of the second scattering holes are downwards, so that a thermocline is not directly impacted in water absorption and water drainage, and the cold accumulation efficiency is improved.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to a water distribution device for a water cold storage system. Background technique [0002] Water-cooled air-conditioning is an energy-saving air-conditioning method that utilizes the peak-to-valley electricity price difference of the power grid, uses chilled water hosts to store cold at night, and stores the cooling capacity in the pool. During the day, the pool cools down and the host runs off-peak. The cold storage tank of the water storage system forms a heat and mass exchange layer between the high-temperature layer on the top plate and the low-temperature layer at the bottom, which is the thermocline layer, and a stable and small-thick thermocline layer is the key to improving the efficiency of cold storage. The water distributor is One of the main factors affecting the heat and mass exchange layer. At present, the water distributor generally adopts H-type, gossip-...

AI Technical Summary

Problems solved by technology

At present, the water distributor generally adopts H-type, gossip-type or plate-hole type, etc., but due to the structural limitations of these types of water distributors, it cannot guarantee that the water absorption and outlet water will spread throughout the entire cross-section of the cold storage tank in a short time, and each There is a relatively large speed difference in the water flow at the position, resulting in a large flow of water in the pool, and it is easy to generate a thicker and less stable thermocline
