PANASONIC Panasonic A/W Heat Pump Aquarea K HP, 1ph, 5 kW, Outdoor Unit – WH-UDZ05KE5

Air-to-water heat pump in split design

Description
Air-to-water heat pump for heating, domestic hot water preparation, and cooling (cooling mode can be activated via settings), consisting of an outdoor unit and an indoor unit (combi hydro module), which is a combination of a hydro module and a hot water tank.

Outdoor unit
Outdoor unit for air-to-water heat pump in split design, 230 V, R32
Housing made of galvanized and stove-enamelled sheet steel RAL 7016, for outdoor installation, removable housing cover for easy access to internal components. Base plate with mounting tabs and condensate opening.
Axial fan with continuously variable DC motor and a sound- and flow-optimized plastic impeller.
The system is optimized for R32 refrigerant with low global warming potential. Air-cooled heat exchanger made of copper pipes with corrugated aluminum fins with coating. Double-rotary compressor, sound-insulated and vibration-damped mounted, and equipped with a pressure-side silencer. Electronic expansion valve, 4-way reverse cycle valve, filter drier, and shut-off valves with test port. Factory tested for pressure resistance and leak tightness and pre-filled with refrigerant. Long line lengths up to 40 m and height differences up to 30 m between indoor and outdoor unit are permissible.

Hydraulic circuit
Plate heat exchanger made of stainless steel. Circulating pump as Panasonic high-efficiency pump with DC motor, continuously controlled. Flow monitoring. Vortex flow meter for dynamic adjustment of water flow in relation to the specified temperature spread, integrated dirty water magnetic filter for the water circuit, electric heating rod with thermal overcurrent trip. Safety and vent valve, water pressure sensor for measuring system pressure. 10-liter expansion tank. 3-way valve for switching between hot water mode and heating or cooling mode. The maximum water outlet temperature at the combi hydro module is 60 °C and is reached even down to -10 °C ambient temperature. The minimum water outlet temperature in cooling mode is 5 °C. Heating operation up to -20 °C, cooling operation up to +10 °C ambient temperature possible. The maximum water temperature in the domestic hot water tank is 65 °C.

Connections
Connections for refrigerant lines as well as for flow and return (heating/cooling), cold water inlet and hot water outlet of the hot water tank are routed in a row side-by-side upwards out of the unit.

Control
Modulating compressor output adjustment via INVERTER+ control electronics. Temperature sensors for outdoor temperature, compressor, hot gas and suction line temperature, and evaporator temperature. Higher efficiency, as the compressor starts in partial load operation and the compressor frequency is increased if necessary, reverse cycle for rapid and efficient defrosting of the outdoor unit heat exchanger. Improved defrosting behavior through bypass defrosting. Communication modules for optimal data exchange with the hydro module. Electronic manometer provides value in electronic form for transmission via WLAN.

Optional board (CZ-NS5P) for additional functions:
• Control input for external on/off switching
• Control input for external room thermostat
