Embodiment 1

[0018] A temperature control system such as figure 1 As shown, it includes a temperature controlled unit and an energy temporary storage device (the part in the dotted line box); the energy temporary storage device includes a phase change material, a phase change container containing the phase change material, and a refrigeration unit that can act on the phase change material to change the phase of the phase change material or heating equipment; the phase-changing container is connected to the temperature-controlled unit, and adjusts the temperature of the temperature-controlled unit. The system has two working modes: cooling mode and heating mode. 1. The temperature controlled unit needs to be refrigerated. When the energy price is low, the refrigeration or heating equipment will make the phase change material in the liquid phase inside become a solid phase. When the energy price is high, it will be a solid phase phase change material and a temperature controlled unit. Heat ...

Abstract

The invention, which relates to a temperature control technique for communication cabinets or communication rooms, discloses a temperature control system. The system comprises a temperature-controlled unit and a temporary energy storage device; the temporary energy storage device comprises phase change material, a phase change container for containing the phase change material and a phase changercapable of changing the phase of the phase change material; the phase change container is connected with the temperature-controlled unit; when the price of energy is low, the temporary energy storagedevice stores energy, and when the price of energy is high, the temporary energy storage device releases energy to regulate the temperature of the temperature-controlled unit. The invention solves the technical defect that the conventional temperature control system cannot sufficiently utilize cheap energy, and thereby the operation cost is greatly reduced.

Description

【Technical field】 [0001] The invention relates to a temperature control technology, in particular to a technology for reasonably utilizing energy in temperature control of a communication cabinet or a communication machine room. 【Background technique】 [0002] Systems such as solar energy, wind turbines, and wind and solar systems have periodic and uncertain mixed characteristics, resulting in instability and imbalance in energy output of the system; similarly, special periods such as hot summer, cold winter, holidays, and day and night often lead to peaks and valleys of energy consumption. The departments that provide energy often use price adjustments to control and regulate energy consumption. For example, the difference in electricity charges caused by the periodic peak and low peaks of electricity consumption during the day and night. [0003] Communication cabinets or communication machine rooms often require heating or cooling equipment to control the internal temper...
