Hybrid Refrigeration Unit

Abstract

The present invention relates to a hybrid refrigeration device formed into a small size suitable for home use, which can not only prepare cold water while reducing energy consumption by using waste heat through cogeneration or hot water obtained from solar energy, but also can cope with radiative cooling prevent condensation on the floor or ceiling when condensation occurs on the surface, and at the same time, floor cooling and heating can be selectively performed using existing hot water heating equipment, including dehumidification cooling devices and cold water supply devices, so The dehumidification and refrigeration device includes: a dehumidification and refrigeration box, which is divided into a dehumidification and refrigeration channel and a regeneration channel; a dehumidification rotor is arranged to be able to rotate across the dehumidification and refrigeration channel and the regeneration channel, and is used to remove the air flowing in through the dehumidification and refrigeration channel The moisture contained in it; the heat exchanger is used to heat the air passing through the regeneration channel for the regeneration of the dehumidification rotor; the cooler is used to make the air dehumidified after passing through the dehumidification rotor Through the water sprayed by the water injection device, thereby utilizing the latent heat of evaporation of water to prepare cold water; the fan is used to forcibly blow the air in the dehumidification refrigeration passage and the regeneration passage; the cold water supply device collects the water prepared by the cooler Cold water is circulated so that the cold water flows through the 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, so The return water temperature is high, and because 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.
