Technology that adds thermal storage tank to the heat pump system
for cooling, heating, and water supply
Client / Market
- Cooling, heating and hot water supply market in residential and industrial sectors
Necessity of this Technology
- Existing small sized ice and cold water storage facility is used for cooling only that annual operation efficiency is very low.
- To improve the annual operation efficiency, a heat pump with thermal storage tank that used for all 4 seasons is applied
Technical Differentiation
- Cooling and hot water supply operation using ice storage + hot water storage system during summer season and hot water thermal storage operation system during other seasons
- Heat pump cycle to generate medium-temperature water of 60℃ to 70℃ during heating
Excellence of Technology
- Prototype production and performance realization through system design and cycle simulation
- Over 12% energy saving compared to conventional boilers (※ Boiler : 85% of efficiency for direct combustion type, electrical production/power transmission efficiency of 40%, 90%, respectively; assumption)
Current Intellectual Property Right Status
PATENT
- Heat Pump System Equipped with Heating and Control Method (KR0721420)
- Thermal Storage Type Heat Pump Design Program (06-01-121-002799 program registered)
KNOW-HOW
- Heat pump design technology generating medium temperature water
- Compressor selection, optimal capacity control technology
- Ice-on typed ice storage and hot water thermal storage tank design technology
- Year-round operation dynamic simulation, performance test
