1.5 Decommissioning
Heat pump systems must be decommissioned in accordance with applicable laws and
regulations. Heat pumps include materials and substances that require special care,
including:
● Refrigerant
● Oil
● Electrical components
● Batteries
● Other materials
The specific considerations for each substance or material are described in the
following sub-sections.
Refrigerant
Depending on the model, the heat pump includes one of the refrigerants listed in table
below.
Refrigerant
R134a
R1234ze(E)
R513A
R450A
R410a
R1233zd
Refrigerants should be recycled, or disposed if recycling is not possible, by a service
provider duly authorized to do so pursuant to local laws and regulations. Depending
on the refrigerant type, refrigerants can be flammable, toxic, or both. In addition,
certain refrigerants have a high global warming potential (GWP) if released into the
atmosphere.
Oil
Waste oil should be delivered to a service provider with the means for processing such
materials in accordance with laws and regulations. Use appropriate precautions to
prevent the oil for leaking or ending up in the environment.
Electrical components
Heat pumps include a wide range of electrical components, such as digital devices,
electric circuits, sensors, and a variable frequency drive. Any such items should be
handled and disposed of as indicated in the instructions given by their manufacturer or
in accordance with local laws and regulations.
Batteries
Batteries can be hazardous for the environment. Consequently, if the heat pump
includes an electronic device with an internal battery, the battery must be appropriately
disposed of.
