This document covers air conditioners, heat pumps and liquid chilling packages, including comfort and process chillers. It applies to factory made units defined in EN 14511‑1, except single duct, double duct, control cabinet and close control units. It also covers direct exchange-to-water(brine) heat pumps (DX-to-water(brine)) as defined in EN 15879‑1.

This document also covers hybrid units as defined in this standard.

This document gives the temperatures and part load conditions and the calculation methods for the determination of seasonal energy efficiency SEER and SEERon, seasonal space cooling energy efficiency ηs,c seasonal coefficient of performance SCOP, SCOPon and SCOPnet, and seasonal space heating energy efficiency ηs,h and seasonal energy performance ratio SEPR.

Such calculation methods can be based on calculated or measured values.

In case of measured values, this document covers the test methods for determination of capacities, EER and COP values during active mode at part load conditions. It also covers test methods for power input during thermostat-off mode, standby mode, off mode and crankcase heater mode.

NOTE 1       The word “unit” is used instead of the full terms of the products.

NOTE 2       The word “heating” is used to refer to space heating.

EN 13611:2019 is replaced by the following:

This document specifies the safety, design, construction, and performance requirements and testing of pressure sensing devices for burners and appliances burning one or more gaseous fuels.

It applies to pressure sensing devices for the measurement of pressures of gases according to EN 437 or air or combustion products for maximum inlet pressures up to 500 kPa (5 bar).

It applies to all types of pressure sensing devices, including electronic, differential and inferential types.

It also specifies requirements for pressure sensing devices which are intended to be applied to steam boilers and as such need to meet increased reliability requirements. These devices are classified as PSD-S in this document.
