Residential districts may install central air-conditioning in the future


Chongqing has sunny and hot summer days, and the air conditioners in some citizens' homes are not turned off for 24 hours. They lamented that if it was not expensive, it would be better to cool down the central air conditioner. Is there a way to reduce the cost of central air conditioning? Dongguan Central Air Conditioning Installation

"For refrigeration equipment, the electricity consumption during the day is large and the electricity consumption is small at night. This forms the peak electricity consumption during the day and the trough of late night electricity. Our ice storage technology can play a role in shifting peaks and filling valleys, while saving energy. Improve the structure of electricity consumption. "

Introduce, ice storage technology refers to making ice and storing cold during the period of low cooling load or low power consumption, and melting and releasing the ice during high cooling load or peak time of power consumption to meet the cooling load requirements. "That is to say, ice cubes are equivalent to batteries. At night, the power consumption is low, and the power load is very low. At this time, the electrical cooling mechanism is used to store ice in the form of ice. During the day is the peak power consumption, the power load is Higher. At this time, the ice is melted to store the stored cold energy, thereby shifting the conventional electricity load from the peak period during the day to the trough during the night, alleviating the power demand and the pressure on the power equipment. " Ventilation and cooling project

Explanation: "Taking the existing air-conditioning system as an example, the air-conditioning in some office buildings, factories, and shopping malls only provides cooling during the day. In this case, it is only necessary to set up cold storage equipment that matches the cooling load and use the trough period for cold storage Can achieve the purpose of not only increasing the refrigeration unit, but also expanding the area of air-conditioning area. "Although the comprehensive investment of ice storage technology applied to air-conditioning is slightly higher than conventional air-conditioning, but the annual operating cost is low, the higher investment can be saved by Annual operating expenses are recovered within a certain period of time. In the future, the annual savings will be the net profit of the enterprise. At the same time, due to ice-storage, the shifting peaks and fills of air-conditioning power usage make the entire grid load more balanced, and the power generation utilization rate of the power station at night is greatly increased, thereby reducing low-level power waste, which is equivalent to saving energy, reducing carbon dioxide, greenhouse gases and sulfur Emissions of pollutants such as substances.
