Mitsubishi Propane Heat Pump For Domestic Use

Mitsubishi Propane Heat Pump For Domestic Use.  Yes that’s right! Mitsubishi Electric has created an air-source heat pump that runs on propane (R290). It can generate heat and domestic hot water at temperatures ranging from 5 to 8.5 kW.

Mitsubishi Electric has unveiled an air-source heat pump designed to replace conventional heat producers and the refrigerant is propane (R290).

What Is Propane?

Propane is a colorless, odorless gas that is part of the family of liquefied petroleum gases (LPGs). It is a hydrocarbon with the chemical formula C3H8 and is often used as a fuel for heating, cooking, and transportation. Propane is compressed into a liquid form and stored in tanks, which makes it easy to transport and use.

What Is Propane (R290)?

Propane (R290) is a colorless, odorless, and non-toxic hydrocarbon gas that belongs to the family of natural refrigerants. It is one of the most widely used refrigerants in the world and is commonly used in household, commercial, and industrial applications.

Propane is classified as a Group 3 refrigerant, which means it has low global warming potential (GWP) and ozone depletion potential (ODP). It is considered an eco-friendly refrigerant because it has a very low impact on the environment and is not harmful to the ozone layer.

Propane is used as a refrigerant in many applications such as air conditioning units, commercial refrigeration, and transportation refrigeration. It is also used as a fuel for heating and cooking appliances, as well as in industry for welding, brazing, and cutting.

However, propane is highly flammable and requires special handling and safety precautions during transportation, storage, and use. It should only be handled by trained professionals who are knowledgeable in its properties and safety guidelines.


How The Propane Heat Pump Work?

Mitsubishi specialist trade partners located in Germany approached them with requests for such a solution,” Dror Peled, Mitsubishi Electric’s deputy division manager, said in a statement. They are now offering their clients entry into the remodeling market with reasonably high flow temperatures based on a natural refrigerant with their Ecodan models with the R290 refrigerant as a monoblock variation.”

In addition, the R290 Ecodan monoblock will be offered in three sizes: 5 kW, 6 kW, and 8 kW. Mitsubishi expects to expand the model series with larger heat outputs of up to 14 kW in the next years, according to a statement.

The heat pump can supposedly provide hot water up to 75 C with external air down to -15 C, or up to 65 C for air temperatures of up to -25 C. “As compared to conventional devices, this represents a major expansion of the regions of use,” Mitsubishi asserts, adding that the ideal flow temperature for best energy-efficient operation is 55 C.

He further stated that the new gadget is built as a monoblock system with the possibility to add a hydro module as an internal unit or a buffer tank for hot water storage with a capacity of 200 or 300 liters.

Due to the particular safety regulations for heat pumps using propane as the refrigerant in residential applications, Mitsubishi is only supplying the heat pump as a monoblock.

In the outside unit, a closed refrigeration circuit runs, requiring no intervention during installation,” the manufacturer had stated. “The outer and internal modules are linked by water-carrying pipes.

Furthermore, the compressors and existing safety precautions within the heat pumps have been structurally altered to ensure the safe installation and operation of the new units. We believe that this is a very good addition in the industry and will help to overcome the burden on using electric power to heat the water in winter season.
