What is BS EN 16905-4-Gas-fired endothermic engine-driven heat pumps?

EN 16905 series is a European Standard that specifies the requirements, test methods, and test conditions for the rating and performance calculation of air conditioners and heat pumps using either air, water, or brine as heat transfer media, with the gas-fired endothermic engine has driven compressors when used for space heating, cooling, and refrigeration, hereafter referred to as “GEHP appliance”.

BS EN 16905 only applies to appliances with a maximum heat input (based on net calorific value) not exceeding 70 kW at standard rating conditions.

BS EN 16905 only applies to appliances having:

Gas fired endothermic engines under the control of fully automatic control systems
Closed system refrigerant circuits in which the refrigerant does not come into direct contact with the fluid to be cooled or heated
Where the temperature of the heat transfer fluid of the heating system (heating water circuit) does not exceed 105 °C during normal operation
Where the maximum operating pressure in the:

Heating water circuit (if installed) does not exceed 6 bar
Domestic hot water circuit (if installed) does not exceed 10 bar

BS EN 16905 applies to appliances only when used for space heating or space cooling or for refrigeration, with or without heat recovery.

BS EN 16905-4 is the fourth part of the series that specifies the calculation of seasonal performance factor for gas-fired endothermic engine-driven heat pumps for heating and/or cooling mode including the engine heat recovery.

Note: The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by BS EN 16905-4.

Who is BS EN 16905-4-Gas-fired endothermic engine-driven heat pumps for?

BS EN 16905-4 on gas-fired endothermic engine-driven heat pumps is applicable to:

Heat-pump manufacturers
Air conditioners manufacturers
Chemical and petrochemical industry
Pharmaceutical industry
Food & Beverages industry
Data centres
HVAC manufacturers
District heating applications
Water heating equipment manufacturers

Why should you use BS EN 16905-4-Gas-fired endothermic engine-driven heat pumps?

Gas-fired endothermic engine-driven heat pumps are essentially air-source heat pumps that are powered by a heat source such as natural gas, propane, solar-heated water, or geothermal-heated water rather than electricity.

If you are a manufacturer or developer of gas-fired endothermic heat pumps, the recommendations in BS EN 16905-4 will assist you in improving the performance and efficiency of your heat pump for effective space heating and cooling.

Demonstrate reliability and credibility with BS EN 16905-4 in gas-fired endothermic engine-driven heat pumps by adopting standardized test methods.
