Background technology
The air-conditioner energy-accumulation technology is a practical complex art that has risen at home since the nineties, it can play the effect of peak load shifting to the electric power of electrical network, help distributing rationally of entire society's resource, simultaneously, because the difference of time-of-use tariffs, the air-conditioner energy-accumulation technology declines to a great extent user's the operation electricity charge, therefore is the technology of benefiting the nation and the people in a top.Energy accumulation air conditioner utilizes energy storage system not need energy or energy is stored in little time with energy in air-conditioning system exactly, and the time big in the air-conditioning system demand discharges this part energy.According to using object and the height that stores temperature, can be divided into cold-storage and accumulation of heat.
Ice-storage air-conditioning is a kind of cooling storage air conditioning system that generally uses at present, tou power price policy in conjunction with power system, in the low power consumption phase at night, employing electric refrigerating machine refrigeration, store making the form of cold with ice, air conditioner load electricity price peak period is with the ice-out released cold quantity, in order to partly or entirely to satisfy the cooling demand by day.Therefore, cooling storage air conditioning system, especially ice-storage air-conditioning have good energy-conservation characteristic and economic benefit.But existing ice-storage air-conditioning has the following disadvantages: because chilled water temperature is lower than conventional air-conditioning, refrigeration working medium (refrigerant) evaporating temperature reduces, and compares with conventional air-conditioning, and compressor is under the lower temperature and turns round, and its operational efficiency is reduced; Simultaneously, because the running temperature of ice-storage system reduces, also make the rated capacity of compressor raise the i.e. corresponding raising of the power consumption of the unit's of obtaining cold.
