Heat recovery type heat pump system, air-cooled simultaneous extraction type, AW-F

Heat recovery type heat pump system, air-cooled simultaneous extraction type, AW-F

An ideal eco system that creates hot water using cooling power. Achieve the ideal system with abundant operating modes.

■ Air-cooled simultaneous extraction type (AW-F) While maximizing the use of exhaust heat, it supports both cooling-only load periods and heating-only load periods with six operating modes. We propose the best energy-saving system. In factories and facilities using air-cooled chillers, the warm air discharged from the air heat exchanger is like wasting energy. Discharge at temperatures higher than the cooling tower or supply water temperature also wastes energy. By effectively recovering heat, energy savings and cost reductions can be achieved.

Recommended use of waste heat recovery heat pumps in cooling systems.

Recommended use of waste heat recovery heat pumps in cooling systems.

Eco Multi Hipon does not waste heat. Not wasting it is amazing.

The "eco multi-hipon" is a heat pump system that reuses energy without waste. It's a waste to discard heat when using a cooling-only chiller. We propose a system that cleverly saves energy by combining it with existing chillers based on the concept of pre-cooling. We offer suitable proposals with a lineup of four types according to the cooling load situation.

  • Heat and Drying Treatment Systems
  • Heat exchanger

Geothermal Facility Case Study: Dongdo Seon Temple (Wonju City, Gangwon Province, South Korea)

Geothermal Facility Case Study: Dongdo Seon Temple (Wonju City, Gangwon Province, South Korea)

Six heat pumps installed considering the drop in temperature during winter! Introduced in the worship area and break room.

The newly constructed temple in Wonju City, Gangwon Province, is located at a latitude similar to that of Niigata Prefecture and is in a region with harsh cold. Primarily, the worship area and rest room have been introduced as part of the "Geo Power System," and considering the low temperatures in winter, six heat pumps have been installed. Due to delays in operation compared to the initial plan, it was not possible to demonstrate the effects during extreme heat and cold periods, but it is expected to perform as designed in the future. 【Case Overview】 ■ Completion: July 2021 ■ Type: Outdoor Air Processing System (No Thermal Storage) ■ GEO Pipes: 12 (Φ380) + Heat Pump (Toshiba) 6 sets *For more details, please refer to the related links or feel free to contact us.
