Technical Field

The invention relates to the field of cold accumulation air conditioners, in particular to an ultrasonic humidifying cold accumulation air conditioner.

Background

The ice storage air conditioning technology can be popularized and used in areas with large peak-valley electricity price difference and relatively gathered personnel.

The ice storage air conditioner utilizes the night low-valley load electric power to refrigerate and store in the cold storage device, releases the stored cold energy in the daytime, reduces the electric load of the air conditioner and the installed capacity of the air conditioning system during the peak time of the power grid, and represents the development direction of the air conditioner in the world at present.

In the existing ice storage system, water is used as a cold storage agent, a glycol solution is used as a secondary refrigerant, and the glycol solution cooled by a refrigerator enters a cold storage heat exchanger of an ice storage tank to absorb and transfer heat of the water in the ice storage tank under a cold storage working condition, and when the cold storage process is finished, the water in the whole ice storage tank is completely frozen into ice. When the cold storage tank is used for cold storage, heat energy in the air is transferred to the secondary refrigerant through the heat exchange equipment of the load terminal, the secondary refrigerant enters the cold storage heat exchanger and then conducts the heat to the ice in the ice storage tank, the ice absorbs the heat and melts, the secondary refrigerant releases heat and cools, and the cooled secondary refrigerant is sent back to the load terminal to continue to complete the cold storage cycle. The ice cold-storage air conditioning equipment in the prior stage is large in size and high in manufacturing cost, and is limited in that the water temperature is reduced to 0 ℃ and the ice cannot continue to store cold, the whole system needs a large amount of water for ice making and cold storage, so that the ice cold-storage air conditioning equipment is limited to the industrial and commercial market and cannot enter the common and civil market, the common air conditioning and the ice cold-storage system cool in the process of cooling, the space around the load must be closed to achieve the best refrigeration effect, the air circulation of the whole space is not facilitated, bacteria and dust are easily accumulated, air is dry, indoor personnel cannot breathe comfortably, meanwhile, when the external environment temperature is lower than the indoor temperature, due to the heat preservation effect of a building wall body, the closed space cannot exchange heat with the external environment, the air conditioning system must operate for a long time, and the comfortable temperature of a human body can be guaranteed. It is therefore desirable to provide a solution to the above-mentioned problems, which can be used in an open environment and which provides cooling only to a local environment.

The existing air cooler is a device for cooling by utilizing a liquid evaporation heat absorption principle, a plurality of wet curtains are arranged inside the air cooler, a small water pump is used for extracting water cooled by a plurality of cold accumulation ice crystals from a water tank, the water is continuously humidified to the wet curtains from top to bottom, when a fan in the air cooler operates, air outside the air cooler is forced to pass through the wet curtains, heat exchange is carried out between hot air and the wet curtains, meanwhile, part of evaporated water is taken away, and meanwhile, the humidity of the air is increased, so that the air cooler has dual functions of cooling and humidifying. However, the air cooler in the prior art needs to cool water by cold accumulation ice crystals and then carries out refrigeration and humidification through evaporation, the efficiency is low, the water consumption is high, the ice crystal cold accumulation amount is low, the water in the whole water tank is cooled, meanwhile, the water tank does not have a heat preservation measure, heat exchange with the ambient environment is realized, the cold in the ice crystals can be consumed quickly, only a short time can be maintained, and the reduction of the ambient temperature is not obvious.
