Net-Zero Commercial / Industrial Air Conditioning

Chillers are the key products featured in this subsector. The product list highlights a variety of net-zero products with cooling capacities ranging up to 1,730kW. Market penetration of net-zero products remains low with major manufacturers failing to provide natural refrigerant-based products. There is an urgent need for manufacturers to develop net-zero compatible solutions.

Energy Efficiency
COP: between 4.0 and 5.5

Type of chiller compressor: Rotary screw
Heat transfer fluid: Glycol, water
Possible temperature range of chilled heat transfer fluid: +4.4°C
Cooling capacity (kW): 266.6 for cooling water from 50°F to 40°F (10°C to 4.4°C) (inlet 10°C, outlet 4.4°C) with ammonia evaporating at 35°F (1.7°C), ammonia condensing at 95°F (35°C)
Unit price: Ammonia chillers in the market are very low volume, so every one is customized. Depending on the application temperatures, the priority of efficiency to cost, priority of cost to low-charge ammonia, etc. there are many different configurations. Frick (JCI) has produced ammonia chillers anywhere from COP of 3.0 to 6.0. However, the cost difference for a specific capacity can range +/- 40% to get higher COP/efficiency values
Training availability: Frick offers full sales, application engineering, and field support for these products on a regional level.
