Description

Technical Field

[0001] The present invention relates to a method and a device for performing secondary cooling, and in particular to a method and a device for performing secondary cooling by utilizing condensed water from a kitchen air conditioner, and belongs to the technical field of air conditioning. Background Art

[0002] In summer, the temperature in the kitchen is high, reaching 35-40 degrees; and when the gas stove is turned on, the temperature can reach 40-45 degrees. There are many oil molecules and water vapor in the kitchen air, and the air humidity is high. Therefore, the kitchen environment is a high-temperature, high-oil, and high-humidity environment, which is very harmful to human health.

[0003] On the one hand, when the current ceiling-mounted integrated water-cooled kitchen and bathroom air conditioner is in operation, the evaporator produces condensed water, which is directly discharged to the outside through the drain pipe. It is necessary to open a hole in the wall to discharge it, or use a water pump to force the drainage directly. This not only wastes the low-temperature condensed water, increases power consumption, and causes energy loss, but also requires a separate drain outlet and drain pipe, which increases the design difficulty and product cost.

[0004] In response to the defects of the above-mentioned kitchen and bathroom air conditioners, the patent technology of our company with publication number CN 212274092 U, application number CN2020205294816, and invention name full-performance air conditioning integrated unit discloses the following technical solutions: the condenser recycles the dehumidified water of the mixed air to the water storage tank at the bottom of the chassis, and pumps it to the water leakage tray A at the top of the evaporator, and then discharges it to the evaporator through the small holes of the water leakage tray A for vaporization to humidify the room. The machine uses the recycled dehumidified water to humidify the room, saving energy and reducing product costs. So, are there other better ways to use the cold water in the chassis of kitchen and bathroom air conditioners?

[0005] On the other hand, traditional air conditioners, including kitchen and bathroom air conditioners, have heat exchangers that play a cooling role and need to be equipped with a separate cold water source. For example, the patent technology with publication number CN 217423483 U, application number CN2022210992732, and invention name Air Conditioning System mentioned that the second heat exchanger can perform secondary cooling on the refrigerant, that is, the second heat exchanger here is equivalent to a supercooler. As we all know, the cold water of the chassis here needs to be provided separately, which is undoubtedly an innocent waste of cold water sources and energy.

[0006] How to make better use of the cold water in the chassis and avoid the innocent waste of cold water for secondary cooling of refrigerant? It is worth discussing. Summary of the invention

[0007] The purpose of the present invention is to provide a method and device for secondary cooling using condensed water from a kitchen air conditioner, in order to address the defect in the prior art of the above-mentioned kitchen and bathroom air conditioners that the cold water in the chassis cannot be reasonably used and a cold water source for secondary cooling of the refrigerant needs to be provided separately, thereby achieving the purpose of saving energy and avoiding unnecessary waste of cold water sources and energy.
