Factor that shows how much influence a refrigerant has on the greenhouse climate. Measured in kg of carbon dioxide per kg of refrigerant.
Refers to the percentage of annual refrigerant leakage from the system.
Refers to the amount of refrigerant in the system
Refers to the economic life of the system.
Refers to what percentage of the refrigerant can be safely used on the day the closure is usually emptied between 0.9-0.95.
The carbon dioxide equivalent purchased per kilowatt hour, ie how much carbon dioxide is produced in the production of electricity.
Refers to the energy supplied to the system on the basis of usually electricity. Consumption refers to all components in the system, including any losses in the system.
The amount that can be recovered from the hot side, ie the energy that would otherwise need to be purchased. If this is not known, about 30% of the condenser heat output of full operation hours can be used.
Refers to the beneficial cooling energy used in the plant.
The beneficial heat energy obtained from the heat pump.
Abbreviated to TEWI and is a way to compare systems and appliances with coolant over its lifetime in addition to using GWP.
Abbreviated to TEWI s is extended from above by doing the calculation even with regard to energy amounts.
Abbreviated to SSEER is a way of calculating the year's efficiency.
