Hybrid device for cooling

Abstract

The present invention relates to a hybrid device for cooling, which is appropriately small for home use, which produces cold water while conserving energy by using hot water which is obtained from waste heat from cogeneration or from solar heat, which prevents condensation on a floor or a ceiling if dew forms on a surface when radiant cooling, and which can selectively cool or heat the floor using an existing hot water heating equipment. The hybrid device for cooling comprises: a dehumidification cooling apparatus further comprising a dehumidification cooling housing which is divided into a dehumidification cooling passage and a regeneration passage, a dehumidification rotor, which is rotatably installed across the dehumidification cooling passage and the regeneration passage, for removing moisture in the air which is introduced to the dehumidification cooling passage, a heat exchanger for heating the air that passes through the regeneration passage for regenerating the dehumidification rotor, a cooler for producing cold water by penetrating the air, from which moisture is removed by passing through the dehumidification rotor, through water which is sprayed by a streaming device and using the latent heat from water evaporation; and an air blower for forcibly blowing the air inside the dehumidification cooling passage and the regeneration passage; and a cold water supply device for collecting the cold water which is produced in the cooler and supplying same so as to circulate through an air-conditioned space.

Description

technical field [0001] The present invention relates to a hybrid refrigerating device, and more particularly to a dehumidifying and refrigerating device that combines a dehumidifying and refrigerating device that prepares cold water or cold air by passing dry air passing through a dehumidifying rotor through a cooler, heating the outside air for regenerating the dehumidifying rotor, or A compression refrigeration device that further cools the cold water, and a cold water supply device that supplies cold water to the air-conditioned space, thereby maximizing the cooling efficiency and minimizing the energy consumption of electricity or hot water supply. Background technique [0002] Due to global warming, the Korean peninsula has migrated to a subtropical climate, so the demand for cooling in summer is increasing day by day, and the instantaneous power consumption is increasing, resulting in an imbalance between the supply and demand of the country's energy consumption.

Problems solved by technology

[0016] Refrigerators are widely used as a device for preparing cold water. However, refrigerators usually have a large capacity and require a large amount of additional equipment such as cooling towers. Therefore, they are more suitable for industrial use than for domestic use, and they have hardly been popularized in the domestic field. , and has the disadvantage of huge power consumption

Although there are examples of using absorption chillers using local heat as a heat source in areas where group energy is used, there is a limit to the improvement of performance due to the low temperature of the heat source, and since it cannot be used at temperatures below 80°C, Therefore, the return water temperature is high, and since the temperature difference between the air supply and return water is small, there is a problem that it is necessary to install cold water piping in addition to the hot water supply piping

[0017] Looking at the papers or academic materials on radiant floor cooling, the problem is that when floor cooling is implemented by supplying cold water, since condensation may occur on the floor, etc. under high humidity conditions, an air conditioner, etc. must be specially installed in addition.
