Flow Control Industries’ DeltaPValves have become increasingly popular for typical hydronic heating and cooling systems. Now you can find them in Water Source Heat Pump applications.
Historically heat pumps have operated with a constant condenser water flow rate, managed by a 2-position control valve in series with a balancing device or flow limiter. Advancements in technology have permitted varying the condenser water flow rate at part load conditions to improve the overall unit efficiency, in addition to reducing the total flow required throughout the system. On/Off control is no longer adequate, and modulating control is required to maximize efficiency.
Pressure independent DeltaPValves provide a cost-effective improvement over the conventional method of control for heat pumps and self-contained units with the following benefits:
Control Type: Modulating
– All benefits of On/Off control type, plus:
– Multiple input control signal types accepted
– High turndown for precise low flow control
– Improved equipment efficiency
– Lower system pump energy consumption
– Lowest total cost of ownership
Backed by a 10-year warranty, DeltaPValves are well suited for this application by providing precise flow control at each unit regardless of system pressure variations or changing operating conditions.
