Tank Construction • - Improved internal tank construction to increase the domestic hot water capacity (insulated divider and new genomströmningsrör). • - New tank charging principle to reduce the need for the immersion heater and to increase the DHW capacity. • - High charging temperature from the heat pump (up to 67°C) enables a high DHW supply without the immersion heater. • - Up to 280 l 40°C @ 8l/min, (before: 125 l) without using the immersion heater. (Summer mode – without heating). • - General impression – reinforced front
Tank Charging Brine out Brine in Charging - top Charging – lower part Return - condenser
Conditions – Tank Charging Charging of the upper tank The DHW charging starts when the upper sensor goes below its set point (factory setting 55 ⁰C), and stops when the sensor reaches its set point. (factory setting 60 ⁰C). The mixing valve closes during the DHW charging, since it has a max Δ of 30 ⁰C. This ensures that the cold water return from the radiators doesn’t inhibit the DHW from reaching a sufficient temperature. Δ T depends on the temperature in the lower tank. charging starts , tank upper sensor (55) charging stops, tank upper sensor (60) lower tank (primary flow temp.) 2 3 1 2 1 3
Conditions – Tank Charging • Charging of the lower tank • The same conditions as for the EcoHeat 3.0, i.e. starts at the primary flow set point (lower tank sensor) and stops at 5 ⁰C above. • When charging, the control system maintains a Δt of 7 ⁰C over the condenser.

Components – Heat Exchangers The plate heat exchangers are from SWEP. The SWEP distribution technology ensures that the evaporator is optimally used. A calibrated distribution system in the evaporator inlet creates pressure drop and generates turbulence, which improves the distribution of the refrigerant. Condenser Evaporator

Thermostatic versus electronic Expansion Valve • Thermostatic expansion valve: • - Optimized within a minor operation area, all other operating points • inside the envelope are “compromises”. • - Can not change its settings for different operation points • Electronic expansion valve: • - Can change its settings for any operating point, and continuously • supervises the refrigeration system. Operates with a pre set value on • the super heating. • Uses constantly the evaporator to its optimum, in relation to the operation, which also means that the operational costs are optimized. • Updating via USB Electronic expansion valve
Components - Compressor • EcoHeat 306 • - Mitsubishi AEH 33 • - The latest version of Mitsubishi heat pump compressors • - Better performance than Copeland ZH15 (EA105, EP5) • New technology – Hot gas super heating • Uses suction gas super heating as well as hot gas super heating => • wider operation area and improved performance • EcoHeat 308, 310, 312 • - Copeland ZH 21, 26, 30 => corresponding to EH 7,5, 8,5, 10,5 • => the 300 series has a higher power than the V3 • A higher cooling power demands a deeper borehole • A higher COP increases the energy outtake from the borehole
Components – Sensors and Pressostats High pressure switch - 31 bar High pressure sensor Supervises the operating area of the compressor and the expansion valve Schrader valves Low pressure sensor Supervises the operating area of the compressor and the expansion valve Suction gas exchanger - Uses the hot condensate to superheat the suction gas => the evaporator is used for evaporation only, and not for superheating
