Efficient use of heat with heat recovery type heat pumps, supporting energy-saving measures and CO2 emission reduction in food factories.
Heat is recovered from hot wastewater (60-80°C) discharged from factories and supplied as saturated steam (100-120°C). It supports remote monitoring and operation. By combining it with an energy management system, it enables energy conservation and optimization of energy use throughout the factory. [Main Features] - Heat is recovered from hot wastewater (60-80°C) discharged from factories and supplied as saturated steam (100-120°C). - By reusing waste heat, the load for high-temperature reheating in boilers can be reduced. - Depending on the amount of steam used, multiple units can be operated in connection (up to 10 units). - It is not subject to the High-Pressure Gas Safety Act, requires no special construction, and is easy to install and implement. [Energy Cost Reduction and CO2 Emission Reduction Effects] - By reusing waste heat, the load for high-temperature reheating in boilers can be reduced. - When generating the same amount of steam using a steam boiler fueled by city gas and a steam generation heat pump, the steam generation heat pump can produce steam with about 50% of the energy consumption of the steam boiler. - This allows for a reduction in boiler fuel costs, enabling energy conservation and CO2 emission reduction in factories.

basic information
- Supports connection operation with multiple units and remote monitoring and operation. Depending on the amount of steam used, connection operation with multiple units (up to a maximum of 10 units) is possible. By connecting to a network, remote monitoring and operation from a central control room or computer is possible, making it easy to grasp and control the operating status. Additionally, by linking with an energy management system, it contributes to the overall energy optimization of the factory. - Easy installation and introduction without special procedures. The steam generation heat pump uses low-pressure refrigerants. Therefore, it is not subject to the High-Pressure Gas Safety Act. There is no need for notifications, selection of safety personnel, or procedures and handling in accordance with laws and regulations by qualified personnel, and no special training or education for pressure vessels is required. There are no special construction requirements during installation, making it easy to set up and introduce.
Applications/Examples of results
Case Study 1: 55.3% Reduction in Energy Costs for Steam Generation and 40.2% Reduction in CO2 Emissions This is a case study of implementation in the clean room air conditioning system of our semiconductor factory. Before the introduction of the steam generation heat pump, we operated a small boiler for humidification, which incurred fuel costs and management efforts. Therefore, we recovered heat from the cooling water of a diesel engine (80°C) and used it as humidification steam for the clean room air conditioning of the semiconductor production line. Compared to the conventional kerosene-fired steam boiler for humidification, we confirmed a 55.3% reduction in energy costs for steam generation. Additionally, we were able to significantly reduce the daily management efforts of the boiler. Case Study 2: 52% Reduction in Energy Costs and 46% Reduction in CO2 Emissions through the Use of Steam Heater Drain This is a case study of implementation in our vending machine factory. By utilizing the steam heater drain in the painting process, we confirmed a 52% reduction in energy costs and a 46% reduction in CO2 emissions compared to before the implementation.

- Recover heat from waste hot water and supply saturated steam We recover heat from waste hot water discharged from factories (60-80°C) and supply saturated steam (100-120°C). Due to its compact design, it can be installed and utilized near various production processes that require steam heating, such as preheating feed water, cleaning, sterilization, and air conditioning/humidification equipment within the factory. This also reduces heat loss associated with extended piping, significantly lowering energy costs and CO2 emissions.
