Embodiment 1

[0018] Embodiment 1: Turn on the power supply of the controller, and the controller will automatically start the refrigeration machine 7 on time according to the start and end time of the set low valley electricity price interval or the upper limit temperature set for the cold storage medium 2, and the cold energy produced by the refrigerator 7 It is transported to the cold exchanger 8 through the connecting pipeline, and the cold exchanger 8 exchanges cold with the cold storage medium 2, and exchanges the cold energy to the cold storage medium 2.

Embodiment 2

[0019] Embodiment 2: Because the refrigerator 7 is an ultra-low temperature refrigerator, the cold storage medium 2 can still maintain good fluidity at -80°C, and there is an insulation layer 6 between the inner shell 3 and the outer shell 4, and the cold energy is The cold storage medium 2 can be stored in an ultra-low temperature state of -80°C.

Embodiment 3

[0020] Embodiment 3: When the cold storage medium 2 reaches the set temperature value or enters a period of time when the electricity price is not low, the controller automatically stops the operation of the refrigerator 7 .

Abstract

The invention discloses a movable electricity transforming cold energy storing and supplying device. The movable electricity transforming cold energy storing and supplying device is composed of a movable shell body, a cold storing unit, a refrigeration unit, a cold energy supplying unit, a cold dissipation device and a controller. The cold storing unit comprises a medium storing tank and a cold storing medium, and is installed on the lower face of the movable shell body. The medium storing tank is composed of an inner shell body, an outer shell body and an insulating layer. The inner shell body is made from a material which keeps stable in structure in an environment of -100 DEG C and is weldable. The outer shell body is made from an ordinary metal material. The inner shell body is installed in the outer shell body, and is provided with a charging inlet formed in the upper face. The insulating layer is composed of an efficient thermal insulation material, and an interlayer space between the inner shell body and the outer shell body is filled with the efficient thermal insulation material. The cold storing medium is a liquid medium which is non-toxic, tasteless, and capable of not corroding and volatizing, and keeps good fluidity at the temperature of -80 DEG C. The cold storing medium is canned in the inner shell body. The refrigeration unit and the cold energy supplying unit are connected to the cold storing medium in the inner shell body, and are controlled through the controller. The cold dissipation device is installed on the upper portion of the movable shell body, and is connected with the cold supplying unit.

Description

technical field [0001] The invention relates to a movable electric conversion cold energy storage and supply device, which belongs to the technical field of cold storage engineering. Background technique [0002] Due to the constraints of technology and other factors, power generation enterprises supply electricity to the grid almost continuously and stably. The electricity consumption market is different. Due to the constraints of nature and the habit of working during the day and resting at night, etc., a large amount of electricity consumption is concentrated during the day, and electricity consumption at night, especially after midnight to early morning, reaches the lowest point of the day. The contradiction between the stable power supply capacity of the power grid and the peak and valley demand of the electricity market is worldwide. The larger the city, the larger the electricity consumption of the country or region, the more prominent the contradiction, the more prom...
