Background

With the development of national economy and the improvement of the living standard of people in China, China has become a large power consumption country, and because the current power production cannot completely meet the power consumption requirements of people, the problem of power shortage can occur in certain time periods and certain areas. Among the many reasons causing the power shortage, the electricity consumption of household appliances, especially the air conditioner, is increasing substantially and is not negligible.

At present, the power consumption of the refrigerator and the air conditioner accounts for 85 percent of the household power consumption. The power consumption of the household air conditioner is more than 400 hundred million kWh per year, which is equivalent to 50% of the maximum power generation of the three gorges hydropower station and exceeds 30% of the load of a power grid.

The continuous increase of the power consumption of cities and towns leads the power peak-valley difference of China to be continuously enlarged, and the centralization of the popularization and the use time of household air conditioners further aggravates the peak-valley contradiction of power supply. The ice cold storage air conditioning technology has obvious peak load shifting effect, so that the ice cold storage air conditioning technology is encouraged and supported by government and electric power departments, and is welcomed by users due to the reduction of electric charge expenditure. With the development of the ice cold storage air conditioning technology becoming mature day by day, the peak clipping and valley filling functions of the ice cold storage air conditioning technology in a large central air conditioning system are widely accepted by people, and the research, development, popularization and application of the large and medium ice cold storage technology for industrial, mining and commercial buildings are continuously developed and perfected.

The distance of cold quantity from the lower part of the heat pipe to the upper part (the fan) is longer, the heat pipe has the characteristic that the larger the distance is, the worse the heat transfer performance is, the cold quantity released by the air port is small, the temperature difference between the ambient temperature and the air outlet temperature is small, the use effect of human cold air is not ideal, the cold air cannot be regarded as an air conditioner in the true sense, the cold air in the cold storage tank is not fully utilized, and the great waste is caused.

In order to improve efficiency, most of the existing ice storage systems are developed towards large-scale and complex, the research on the technology of small-sized ice storage air conditioners suitable for household is not much, and meanwhile, most of the ice storage air conditioners are provided with relatively complex refrigerant circulation loops at the user load end, so that the miniaturization of the ice storage air conditioners has certain difficulty.
