Water-loop heat pumps and net-zero

DSC03023

Designing net-zero-energy buildings for new construction or renovation presents many challenges. It requires analyzing the unique energy use of the entire facility and then designing a system that can reduce the net-energy footprint without sacrificing functionality or comfort. As energy consumption is reduced, onsite renewable energy plays a larger role in efforts to reach the goal of net-zero energy. Water-source heat pumps (WSHPs) can be important in this respect.

Variable refrigerant flow (VRF) HVAC zoning and geothermal systems are two of the most energy-efficient options for heating and cooling available—now, new hybrid assemblies combine the two. This article provides an overview of geothermal (or water-source) with VRF zoning technology and its advantages compared to traditional geothermal systems, air-source VRF zoning systems and conventional HVAC systems. In addition, the article will discuss considerations for specifying water-source VRF zoning systems and provide case studies of successful applications.

New technologies can provide optimal natatorium environmental control and energy savings. Today’s indoor pool dehumidifiers and outside air ventilation systems technology has changed so much over the last decade, a new or retrofitted natatorium stands to save millions of dollars in energy costs over the 15 to 25-year lifecycle of the equipment. Equipment comes with reduced refrigerant charges of up to 85-percent, compressor heat recovery for free pool water heating, exhaust heat recovery for preheating outdoor air, modulating controls for pinpoint temperature and humidity control, glycol heat rejection to dry coolers, and web-based microprocessor monitor, alarms, and control for factory technician review.
