Water distribution device used for cool storage tank and opening and arranging method

Abstract

Disclosed is a water distribution device used for a cool storage tank and an opening and arranging method. The method includes the following steps that (1), through fluid mechanics, the design of thewater distribution device is obtained, and requirements that the Frande criterion number Fr is no more than 1, and the Renolds number Re is less than 2000 are needed to be met, so that fluids of different temperatures in the cool storage tank are made to be gravity flows and a stable laminar flow is formed; (2), for the purpose that the Renolds criterion number is less than 2000, the flow rate v of the water distribution device is obtained according to the following formulas of Q'=Q / (delta t*Cp*rho l) and Re=rho2vd / eta <2000; (3), the maximum flow Q' passing through the water distribution device divides the flow rate v passing through the water distribution device, and the minimum opening number of the water distribution device is obtained; (4), according to the minimum opening number of the water distribution device, and combining with the effective opening length of the water distribution device, the final opening number is determined; and (5), the maximum flow passing through the water distribution device divides the effective opening length to obtain the volume flow rate q of per unit length of the water distribution device, 0 is substituted into a formula of Fr=q / [gh<3>(rho i-rho a) / rho a]<1 / 2><1, wherein the Frande c criterion number Fr is no more than 1 in the formula, and the height h from water distribution holes in the lowest portion of the water distribution device to the inner surface of a bottom plate of the cool storage tank is obtained.

Description

technical field [0001] The invention relates to a cold storage tank, more specifically, to a water distributor used for the cold storage tank and a method for opening and installing the water distributor. Background technique [0002] As a large water storage container for water storage, the cold storage tank is widely used in the field of data centers as a backup cold source for data centers. The use of the cold storage tank is to store cold during the time period of low temperature and low electricity price at night, and to cool down during the period of high temperature and high electricity price during the day, so as to effectively use peak and valley electricity prices and outdoor temperature changes to reduce the power consumption and operating costs of the air conditioning system. [0003] The working principle of the cold storage tank is to use the principle of natural stratification caused by the different densities of cold and hot water. In the case of charging and...

Problems solved by technology

In order to ensure the effect of the cold storage tank, the most important factor is the number and area of ​​openings on the water distributor, but the number and area of ​​openings in the existing water distributor are usually based on the area of ​​the supply and return pipes The number of openings and the opening area are unreasonable, resulting in uneven opening of the water distributor and insufficient overall opening area, which in turn causes water flow disturbance and seriously affects the effective volume of cold storage.
