Heat pumps

unimo can supply hot water in a highly efficient manner by proficiently using heat in the air and water. This heat pump uses a natural refrigerant, CO₂, and the lineup consists of three models: AW, which utilizes an air heat source, WW, which utilizes a water heat source, and AWW, which utilizes both air and water heat sources. Each model can instantly deliver water at 90℃(194℉), and supply plenty of hot water with overwhelming cost performance. The model using water as a heat source is a CO₂ heat pump combining hot water boiler and chiller functions in one package. In addition to plenty of hot water supply capacity, it can be used as only heat pumps with water as the heat source can, providing double the merit. Additionally, the lineup includes a CO2 heat pump that realizes a cold and hot water supply utilizing both air and water as the heat source, a world first. Using the thermal energy of water, this unit can supply cold and hot water simultaneously when air conditioning and process cooling are required during the daytime and summer months. At night and during the winter, when cold water is not normally used, it can produce hot water alone using the thermal energy of air.

The first heat pump air heater in the world to provide high-temperature heating, up to a maximum of 120℃(248℉) , using CO₂ as a refrigerant. It utilizes renewable energy such as cold water, exhaust heat, and well water for process cooling. This is a revolutionary heat pump that can supply hot air needed for drying and heating with overwhelming energy and cost savings, while also contributing to the reduction of CO₂ emissions.
Hot air is supplied without the use of combustion devices such as burners and boilers. Furthermore, the cold water generated simultaneously with the hot air can be used for air conditioning and process cooling, and units can be linked to meet capacity requirements. When hot air in excess of 120℃(248℉) is needed, combining this unit with other heating sources (electric motors, steam, etc.) results in the desired effectiveness.

Pipes are buried in roads and sidewalks. Glycol is then heated to about 15℃ (59℉) with a heat pump and is sent along the pipes to warm the road surface which prevents it from freezing and keeps it dry.
For the heat pump heat source, it is possible to use various renewable energy sources, such as readily available air, groundwater, geothermal energy, lake water, and seawater. Reduced fossil fuel use and CO₂ emissions with this heat pump line-up.

Mayekawa offers a range of ammonia heat pumps offering high quality hot water up to 85℃(185℉).
Available as reciprocating and screw compressor packages these units can act as standalone units using a waste water or geothermal heat source. They can also be integrated into an existing refrigeration system as a heat recovery application.

Supply cold and warm air ranging from 0 to 50℃ (32 to 122℉) to parked aircraft with this cooler. For aircraft maintenance, the engines are turned off, and this cooler will supply cold and warm air as a piece of ground support equipment (GSE).
The cooler can also be used as a power generator and source of power for commercial purposes and is self-powered, meaning it can provide cold and hot air in a wide range of places. In addition to being used with aircraft, it can also serve as a mobile air conditioning unit during disasters, etc.

Take advantage of the features of a heat pump that uses a screw compressor capable of handling a wide range of compression ratios. This unit allows for smooth switching between three modes: cooling, heating, and heat recovery (simultaneous extraction of cold and heat energy). It also contributes to energy saving by using various heat sources such as waste heat and renewable energy such as air, water, and geothermal heat. As a demand measure, it also supports ice thermal storage and can be used for a wide range of air conditioning applications.
Additionally, as the separate heat pump model allows the air heat exchanger and the compressor to be placed in different locations, it can be installed in small spaces. Together with thermal energy storage units it is used for central air conditioning in office buildings and public facilities, and it will support your air conditioning system upgrades.
