Embodiment 1

[0035] (1) Cold storage / cooling release design

[0036] There are four raft foundation areas in the underground space of an actual engineering project, see figure 2 , taking the southeast and southwest raft foundation regions as examples for illustration. According to the relative position of the machine room and the raft base area, the inlet and outlet of the water cooling storage in the southeast raft base area are designed on the west side of the area, and the water cooling storage inlet and outlet of the southwest raft base area are designed on the east side of the area. And in line with the principle of maximizing the use of raft foundation space, the water flow lines in the southeast and southwest raft foundation areas are designed. Two water flow channels are designed in the southeast raft base area, respectively image 3 Three arrows and two arrows in . The southwest raft base area is only connected by a water flow channel, see Figure 4 . The flow direction of t...

Abstract

The invention relates to a raft foundation chilled water storage device. The raft foundation chilled water storage device comprises a plurality of building raft foundation trough bodies which are arranged adjacently. The side wall of each building raft foundation trough body is provided with water through holes, and chilled water is guided to flow among the raft foundation trough bodies through the water through holes. The raft foundation chilled water storage device has the advantages that a labyrinth cold accumulation mode is put forward, an underground raft foundation area is fully utilized for chilled water storage, the initial investment for a system is reduced, and the use space is saved; the operation possibility of a non-occupation type cold accumulation mode is reserved, when not ideal, the actual operation effect of the labyrinth chilled water storage mode can be switched to the non-occupation type cold accumulation mode for operation, and the performance reliability is improved; a heat preservation form of polyurethane on-site foaming is adopted in heat preservation of the raft foundation trough bodies, and the advantages of good heat preservation and insulation effects, good chemical stability and convenient construction are achieved; a polyurea waterproof system is adopted in the waterproof technology and has the advantages that solidification is quick, the construction efficiency is high, and the ageing-resistant performance, salt corrosion resistance, thermal stability, binding power and the like and good.

Description

technical field [0001] The invention relates to a building raft foundation water cooling storage device and a water cooling storage method using the building raft foundation. Background technique [0002] Since the 1970s, the worldwide energy crisis has prompted the rapid development of cold storage technology. The application of cold storage technology in building air-conditioning system can reduce the equipment capacity and reduce the peak load of power supply. The promulgation of the peak and valley electricity price policy and its continuous development and improvement will create a good external economic environment for the development and application of cold storage air conditioners in my country, and the application of cold storage technology in my country will form a continuous development trend. [0003] Water cold storage, using the sensible heat of water to store cold, water cold storage air-conditioning systems have been successfully put into use as early as the...
