氷機を設けてある空調用冷熱蓄熱設備に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention aims to reduce the operating load on the refrigerator during cooling during the daytime, etc. by making and storing ice during non-cooling periods such as at night, and converting cold heat into latent heat. This is equipment that stores heat in the form of a heat storage tank, in particular, a heat storage tank with a water return port from the air conditioning load at the top and a water outlet to the air conditioning load at the bottom, and an ice maker that supplies ice blocks to the heat storage tank. This article relates to cold heat storage equipment for air conditioning.

する。However, in the early stages of ice storage operation, when the ice maker is operated to store ice blocks in the heat storage tank during non-cooling periods such as at night, there are few ice blocks, and each ice block is separated into small chunks and flows into the water in the heat storage tank. However, at the end of the ice storage operation, a large number of ice blocks overlap one above the other, and are squeezed from above and below by their own weight and buoyancy and fuse together, forming one giant ice block. Therefore, in conventional equipment, when the cold water in the heat storage tank is used for cooling operation based on the air conditioning load after the ice storage operation is completed, as shown in Figure 5, the water is returned from the water return port to the heat storage tank. As the water flows down, among the huge ice blocks,
Only the portion near the water return port that is hit by the flowing sewage from the water return port is dissolved by contact with the water flowing from the water return port, and eventually a hole (A) is formed in the vicinity of the water return port that reaches the water layer below. Once such a hole (A) is formed, a short path is created in which the flowing water directly reaches the water layer under the tree through the hole without contacting the ice, and is taken out from the water outlet. When such a short path occurs, the cooling of the returned water by ice storage depends only on the contact of the water with the bottom of the huge ice block, which reduces the cooling efficiency of the water due to contact with the ice and reduces the return water cooling efficiency. Not only is the water outlet temperature high (relative to the amount of ice stored), but the water outlet temperature fluctuates.
本発明の目的は、前記のショートパスを防止し、蓄氷に
よる水の冷却を効率良く、安定して行えるようにする点
にある。An object of the present invention is to prevent the above-mentioned short path and to efficiently and stably cool water by storing ice.
本発明による空調用冷熱蓄熱設備の特徴構成は、前記還
水口を、前記蓄熱槽内のほぼ全域に還水を散布する散水
ノズルから構成してある点にある。そして、それによる
作用・効果は次の通りである。A feature of the cold heat storage equipment for air conditioning according to the present invention is that the water return port is constituted by a water spray nozzle that sprays return water over almost the entire area within the heat storage tank. The effects and effects thereof are as follows.

が小氷塊の全体によって効率良（冷却される。The ice stored in the heat storage tank by the operation of the ice maker becomes one giant ice block, but that giant ice block is made up of many small ice blocks created by the ice maker that are squeezed from above and below by their own weight and buoyancy, and then melted. Since it is an aggregation of small ice blocks that have landed, the huge ice block has many minute gaps that penetrate it in the vertical direction and are evenly distributed throughout. Focusing on this point, by configuring the return water port from the air conditioning load with a nozzle, the return water is evenly distributed over almost the entire area inside the heat storage tank. At times, when the ice storage is in the state of a huge ice block, water is evenly distributed over the entire top surface of the huge ice block, and reaches the water layer under the tree through each of the many microscopic gaps that exist evenly throughout the huge ice block. Flow down. As a result, the returned water comes into contact with the top surface of the giant ice block, the ice wall surface around the minute gaps, and the bottom surface of the giant ice block, so that the contact surface with the ice is large and it is efficiently cooled. On the other hand, when we look at ice storage, the entire top surface of a giant ice block comes into contact with water and melts evenly, and each microscopic gap becomes evenly thick. Even after separation into small ice blocks, the return water is distributed almost evenly over the entire upper surface of the water layer containing small ice blocks. Good (cooled.
要するに、還水を蓄熱槽内の全体に分散供給するように
したため、還水によって巨大氷塊の状態にある蓄氷を多
数の小氷塊に分断でき、そして、巨大氷塊の状態、小氷
塊の状態のいずれにおいても、還水を蓄氷に十分に接触
させて効率の良い遣水冷却を行い、遣水が蓄氷で冷却さ
れずに、出水口に至るショートパスを防止できるのであ
る。In short, since the returned water is distributed and supplied throughout the heat storage tank, the returned water can divide the ice stored in the state of a huge ice block into many small ice blocks, and the state of the large ice block and the state of small ice blocks can be changed. In either case, the return water is brought into sufficient contact with the ice storage to perform efficient water cooling, and it is possible to prevent the water from passing through the water outlet without being cooled by the ice storage.

熱設備を提供できるに至った。As a result, according to the present invention, by storing ice, cooling water can be efficiently and reliably cooled, and the water outlet temperature can be made sufficiently low and stable, and the cooling temperature can be controlled. We have now been able to provide a cold/heat storage facility for air conditioning that can easily, reliably, and accurately perform the following steps.

By repeating this process, cube-shaped, plate-shaped, tubular, and rod-shaped blocks of water ice are made. The water used as the material for the ice is the water pumped up by the pump (Pl) in the heat storage tank (6). Note that the ice maker (7) may be one that makes large blocks of ice and shaves or breaks them into small ice blocks.

(6) When the cooling operation is performed by returning the water inside, the returned water is distributed and supplied to the entire top surface of the huge ice block, passing through all the minute gaps formed evenly on the huge ice block, and passing through the water layer under Kinoshita. This will lead to. As a result, the return water is efficiently cooled by contact with the top surface of the giant ice block, contact with the surrounding ice when flowing through minute gaps, and contact with the bottom surface of the giant ice block. As the ice melts evenly, each microscopic gap gradually expands, and finally, the giant ice block breaks up at the microscopic gaps and becomes many small ice blocks.
