improved capacity compared to previous model 1/2 product features improved capacity operation range domestic hot water cold ambient Improved capacity Higher compressor frequency improved capacity compared to previous model Example new model ERLQ016CAW1 compared to previous ERLQ016BAW1 installed in a 14kW house at Vienna, Austria. HP and system capacity are higher at low ambient temperatures. Less need of backup heater = higher system COP Increased heating capacity ERLQ016C ERLQ016B +2 kW @ -15°C Integrated COP ERLQ016C ERLQ016B Animation volgorde Thermal output (kWh/C°) NO BUH support needed!

Compressor operation till -25°C EXTENDED OPERATION RANGE HEATING MODE At low ambient + high leaving water temperature, the liquid injection prevents the compressor from getting too hot due to high discharge temperature. New in this model is an electronic expansion valve with optimized injection quantity. Avoid too high discharge temp by low liquid injection Liquid injection by EEV (precise control) Pressure (Bar) Enthalpy (KJ/KG) X Eerst system layout tonen, dan pas mollier?

Improved resistance at colder Tambient: hot gas pass 1/5 product features improved capacity operation range domestic hot water cold ambient Improved resistance at colder Tambient: hot gas pass HOT GAS PASS Pressure (Bar) Enthalpy (KJ/KG) X Hot gas injection valve Hot gas pass in bottom plate to keep the temperature of the bottom plate positive. All drain holes are open so drain can get out of the unit Limited operation (only shortly before and during defrost cycle hot gas will pass through the hot gas pipe) Hot gas pipe
Solution against ice build up from bottom 2/5 product features improved capacity operation range domestic hot water cold ambient Improved resistance at colder Tambient: sub cool pass SUB COOL PASS Current system New system sealing distributor Additional sealing at the bottom of the heat exchanger to reduce the cooling by airflow Before the refrigerant pipe is split up by the distributer to the hairpins, the pipe passes through the bottom of the coil. Solution against ice build up from bottom TEST RESULT (48 hrs, -15℃, 100RH% + 12 hrs, -10℃, 100RH%) Bottom of H/E is free from ice Current system New system capacity: 100W continuous operation if Ta is below 5°C capacity: 35W operation only during defrost (3 min.) and max. 3 times per hour Estimated Yearly consumption = 241.7 kWh/y Estimated Yearly consumption = 17.1 kWh/y In extreme conditions, still the electrical bottom plate heater is needed, but smaller size (from 100W reduced to 35 W) Bottom heater Consumption of the electrical bottom plate heater: 90 % Example for 14kW house at Vienna, Austria
