The National Ground Water Association (NGWA) has announced plans to develop an American National Standards Institute third-party accredited standard for the construction of vertical boreholes used in closed-loop ground source heat pump systems.
The Versatec™ Base combines high efficiency and value-added features in a compact water-source heat pump for water loop and geothermal applications. Tthe heat pump model is said to exceed American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 90.1 efficiencies.
The XT Series Models 024-048 packaged geothermal heat pumps are now standard with the all-aluminum microchannel air coil by Delphi®. According to the manufacturer, the all-aluminum coil utilizes 40 percent less material than a standard tube-and-fin copper/aluminum coil.
Bob and Tim have arrived back at the apartment building where they have been working for several days inspecting and making necessary repairs to the building’s split-system heat pumps. Bob said, “Check the list for another unit that seemed to have a problem and let’s take a closer look at it.”
Since the tax credit program became available, all types of geothermal options have been on the minds of the building community. The earth loop, often referred to as the refrigerant loop, may be installed in three different configurations: diagonal, vertical, and horizontal.
The U.S. Department of Energy (DOE) has announced the availability of a report — Hybrid Ground-Source Heat Pump Installations: Experiences, Improvements and Tools — that DOE says demonstrates hybrid ground-source heat pumps (GSHP) as a viable solution to reduce energy use in commercial buildings.
EnLink Geoenergy Services, a leading builder of geothermal heat pump (GHP) systems, announced that it has won a $3.8 million contract for a portion of the Ball State University GHP system in Muncie, Ind., said to be the largest geothermal energy system in the country.
Hill Phoenix Inc., a Dover Company, has announced the acquisition of Denmark-based Advansor A/S. The Danish company specializes in the design and manufacture of CO2 transcritical refrigeration and heat pump systems for supermarkets and light industrial applications.
Bob and Tim have arrived at the apartment house that they have been working at for the last several days. They’ve gone to the roof where the outdoor units are located. There are 60 heat pumps that use R-22 as the refrigerant. They start with Unit No. 2.
