PANASONIC Panasonic R290 Aquarea M Air-to-Water Heat Pump, T-CAP, 30 kW, Outdoor Unit – WH-WXG30ME8

Panasonic Hydrosplit Aquarea Big T-CAP heat pump, three-phase, inverter-controlled, R290
Controller module
Controller module for air/water heat pump in hydrosplit design for use with R290 and with a three-phase 400 V / 50 Hz mains connection

Operating modes
Heating, domestic hot water, cooling (cooling mode can be activated via setting)

Outdoor unit
Outdoor unit for air/water heat pump in hydrosplit design with R290 refrigerant and a three-phase 400 V / 50 Hz mains connection. The casing is made of galvanized and stove-enamelled sheet steel in anthracite grey (RAL 7016), is suitable for outdoor installation and has a removable casing cover for easy access to internal components. The base plate has mounting tabs and condensate openings.
The axial fan has an enlarged fan diameter for constant air flow to reduce the fan speed and is driven by a continuously variable DC motor and a sound and flow-optimized plastic impeller. Densely mounted control box at the top for safe water drainage. A gas/liquid separator is present in the outdoor unit. Pressure resistance and leak tightness are factory tested and provided with an environmentally friendly refrigerant base filling. The design specifications according to IEC 60335-2-40: 2022 are met. The heat exchanger consists of copper pipes with pressed-on Bluefin-coated aluminium fins. A 4-pole synchronous motor compressor and a 4-point vibration damper device as well as soundproof compressor material ensure a reduction of vibrations and noise. Electronic expansion valve, 4-way reversing valve, filter dryer and shut-off valves with test connection are included. Pipe lengths up to 30 m and height differences up to 30 m between indoor and outdoor unit are permissible.

Hydraulic circuit
The plate heat exchanger is made of stainless steel. The circulation pump, a Panasonic high-efficiency pump, is continuously controlled with a DC motor. Flow monitoring is present. A vortex volume flow meter for dynamic adjustment of the water volume flow depending on the specified temperature spread is present, as well as an integrated dirty water magnetic filter for the water circuit and a thermal overcurrent release. Up to three electric heating elements with 3 to 6 kW output can be installed on site in the domestic hot water tank or buffer tank. Built-in safety and vent valve as well as water pressure sensor for measuring the system pressure. Flow temperatures up to 75 °C are possible. The operating range in heating mode extends down to -28°C. A water outlet temperature of 55°C is reached at an outdoor temperature of up to -25°C. In cooling mode, the operating range is between 10°C and 43°C outdoor temperature. With T-CAP technology, the nominal heating capacity remains constant at an outdoor temperature of up to -20°C. System safety is increased by the hydraulic connection to the indoor unit and the separation of refrigerant in the outdoor unit as well as electronics in the indoor unit.

Control
Modulating power adjustment of the compressor through inverter control technology.
High energy efficiency due to operation start in partial load range and demand-controlled increase of frequency. Equipped with temperature sensors for outdoor temperature, compressor, hot gas and suction line temperature as well as evaporator temperature. A circuit reversal procedure ensures rapid and efficient defrosting of the outdoor unit heat exchanger. Communication modules for optimal data exchange with the hydro module.
Separate heating and/or domestic hot water control with a clear control panel and easy-to-understand symbols as well as plain text menu displays in 26 different user languages. Continuous display of outdoor and flow temperature as well as outdoor temperature-controlled adjustment of the flow temperature in heating mode are present. Temperature sensors for condenser, flow and return temperature. Display of system pressure, weekly timer for time-dependent on/off switching and operating mode pre-selection. A programmable timer is available for thermal disinfection. The electric auxiliary heating is controlled as required.
