Problems solved by technology

Open-type external ice-melting systems generally have defects such as large head of the cooling pump, unavoidable backflow of water flow at the end of the room after the pump stops, water flow reversing solenoid valve and water volume adjustment electric valve are subjected to high hydrostatic pressure, and difficult to open and adjust. In the actual ice storage air-conditioning system, the above defects are overcome by increasing the secondary heat exchange between the ice tank air-conditioning water and the system air-conditioning water. Air-conditioning water system water pump, pipe diameter and terminal equipment specifications, reducing the total system cost and other issues

Embodiment 2

[0024] attached image 3 And attached Figure 4 It is another embodiment of the present invention, which is called a vertically closed external ice-melting ice storage tank. The internal structure of the housing 1 is exactly the same as the above-mentioned embodiment. The difference is that the installation form in use is vertical installation. Therefore, in this embodiment, the housing 1 is connected with the upper head 19 and the bottom head 20. The upper head 19 is equipped with a brine inlet 5, a brine outlet 4, and an air-conditioning water outlet pipe 7. The bottom end 20 is Air-conditioning water inlet pipe 6 is provided. The air-conditioning water outlet pipe 7 is arranged on the upper top of the upper head 19 , and the air-conditioning water inlet pipe 6 is arranged on the lower top of the bottom head 20 . The usage method of this embodiment is the same as the usage method of the foregoing embodiment, and will not be repeated here.

Abstract

The closed outer ice-thawing ice accumulating tank includes casing, ice coil pipe, secondary refrigerant liquid separating pipe and secondary refrigerant liquid collecting pipe. Structurally, the present invention features that inside the casing with closed ends, the ice coil pipe is the secondary refrigerant passage formed by bent pipes and straight pipes and is closed inside the casing by the pipe sheets with water flow passage. The space between the ice coil pipe and the casing form the air conditioner water passage, inside which there are several crossed radial water flow deflecting boards. The ice coil pipe assembly inlet is connected to the secondary refrigerant liquid separating pipe, while the ice coil pipe assembly outlet is connected to the secondary refrigerant liquid collecting pipe. All the pipe channels are led out the ends separately. The air conditioning system of the present invention has high reliability, low system cost.

Description

technical field [0001] The invention relates to the technical field of ice storage air conditioners, in particular to ice storage tanks in ice storage air conditioners. Background technique [0002] The ice-storage air-conditioning system uses cheap power during the low-load period of the power grid, such as nighttime power, and stores the cold energy produced in water through the refrigeration system, freezing the water into ice; The cold energy in the ice is released to supply cooling to the air-conditioning system, thereby reducing the demand for electricity during the high-load period of the power grid, and realizing the air-conditioning system that "shifts the peak and fills the valley" of the power system. According to different ice-making methods, ice-storage air-conditioning systems are mainly divided into two categories: dynamic ice-making and static ice-making. The dynamic ice-making system is rarely used in practical engineering because it is prone to pipeline bl...
