The Italian manufacturer said its new WWMG heat pump system has a coefficient of performance of up to 4.98 and an energy efficiency of 16.30 BTU/Wh.
Aermec North America, part of Italy-based Aermec, which itself is part of the Giordano Riello International Group has launched a new water-cooled heat pump system that it claims provides more heating and cooling per m2 than any other heat pump on the market.
“Thanks to its compact design, it will play an important role in the renovation of existing residential, commercial and industrial buildings in urban areas where powerful, efficient heating and cooling technology solutions are needed for buildings with limited space,” the company said in a statement.
The new product has a modular design, with up to 36 units stackable to achieve a total production of more than 1000 tons per bank. Each unit depends on 2 independent 15-ton refrigerant circuits with a nominal capacity of 30 tons each. The number of tons does not refer to the weight of the unit, but to the tons of heat that a building needs.
The WWMG system has a cooling capacity of 30.24 tons and an energy efficiency class (EER) of 16.30 BTU/Wh. The heating capacity is 42.61 BTU/Wh and the coefficient of performance (COP) is 4.98. It also features an Integrated Part Load Rating (IPLV) of 21.16 BTU/Wh. The IPLV refers to the efficiency of the system based on its performance under different load conditions, not just the maximum capacity.
The heat pump uses R-454B as a coolant and, according to the manufacturer, can supply hot water at a temperature of up to 60 degrees Celsius. It uses a water-cooled chiller and flow switches that reportedly prevent damage due to insufficient water flow. In addition, it uses butterfly valves on both hydronic circuits to isolate individual units from the bank, improving ease of maintenance.
“The refrigerant circuit can be easily disconnected from the unit, preserving all functions of the water circuit and ensuring correct operation of the system,” the company said. “The modules are easy to install and connect together thanks to the connections
with groove connections on the water circuit.”
Each WWMG unit measures 130 cm x 160 cm x 118 cm and weighs 900 kg.
“Whether residential or commercial, buildings in busy cities often face the difficult challenge of having limited available space for HVAC systems, yet requiring powerful, reliable heating and cooling solutions to keep residents comfortable all year round,” the company said. “Fortunately, the WWMG is fully capable of maintaining comfortable temperatures in these buildings year-round without overloading available space, while meeting the necessary local compliance specifications.”
