AIR-TO-WATER HEAT PUMP WITH INTEGRATED HYDRONIC MODULE 30RQM/30RQP 160-520
Features and advantages
Very economical operation
High unit full and part load energy efﬁciency and efﬁcient design of the water side: - Standardised Eurovent values in accordance with EN 14511-3:2013 EER up to 2.9 and ESEER up to 4.35 (30RQP version) - 30RQP and 30RQM ranges are compliant with EU Eco-design Tier 1 Minimum Efﬁciency Performance Standards (MEPS) in heating that apply from September 2015 - 30RQP range and 30RQM sizes 430-470-520 are compliant with EU Eco-design Tier 2 MEPS in heating that apply from September 2017 - Multiple scroll compressors equipped with a high-efﬁciency motor that permit exact matching of the capacity to the load - Electronic expansion device permitting operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface (superheat control) - Air heat exchanger with Greenspeed® variable speed fans (30RQP version) - Low pressure drop brazed plate heat exchangers (pressure drops < 45 kPa at Eurovent conditions). Speciﬁc control functions to reduce unit energy use during occupied and unoccupied periods: - Internal time schedules clock: Permits heat pump on/off control and operation at a second set point - Automatic water set-point offset based on outside air temperature or room air temperature via an option - Floating high-pressure management - Variable-speed fan control - Cooling and heating demand limitation. Refer to control chapter for more information. Greenspeed® variable-speed pump to reduce pumping energy use up to 2/3 (option recommended by Carrier): - Elimination of the energy losses caused by the water ﬂow control valve by the electronic setting of the nominal water ﬂow - Energy savings during stand-by periods or part-load operation by automatic water pump speed reduction. Pump motor energy use varies as the cube of the speed so that only 40% speed reduction can reduce energy consumption by 80% - Improved unit part-load performance (Increased SCOP and SEER values with variable water ﬂow following EN14825). Refer to hydronic option chapter for more information.
Extra energy savings through partial heat recovery option that permits free hot water production. Reduced maintenance costs - Fast diagnosis of possible incidents and their history via the control - R-410A refrigerant is easier to use than other refrigerant blends.
