Ice Air’s high-efficiency Console Water Source Heat Pumps are rated at 13+ EER and use R-410A refrigerant.

Fujitsu General America is introducing a new Halcyon split-system heat pump line with equipment that achieves up to 27.2 SEER, making them the most energy efficient mini-splits available today, and more than twice the DOE’s minimum efficiency standard of 13 SEER, says the company.

The RPHE-093G includes 9,300 Btuh heat pump capacity and two electric heaters at 3,400 Btuh each for up to 16,100 Btuh of integrated heat; cooling capacity is 9,300 Btuh.

ClimateMaster is now offering the Tranquility Compact Series with a vertical cabinet. It is available in sizes 6 tons through 10 tons with belt-drive blowers, multiple cabinet configurations, and efficiencies to meet new ASHRAE building standards.

The Tranquility Split Geothermal System consists of the Tranquility Outdoor Split Unit (TTP) and the Tranquility Air Handler (TAH).

The ClimateMaster Tranquility 22 Digital Series incorporates high-end features like a two-stage compressor, Energy Star Tier 3 efficiency, variable speed fan, communicating digital controls and true plug-and-play functionality at a very competitive price point, says the company.

High-efficiency horizontal and vertical water-source heat pumps in the A-Vintage line offer EER up to 21 and COP up to 5.6. The horizontal (½ to 6 tons) and vertical (1 to 6 tons) water-source heat pumps provide energy efficiency in geothermal and boiler/tower heating and cooling applications.

Offered in sizes 6 through 10 tons with belt-drive blowers, the Tranquility Compact Series is available with a vertical cabinet. The series has an extended range refrigerant circuit, capable of ground loop applications, ground water applications, as well as water loop (boiler-tower) applications.

The textbook HVACR 401: Heat Pumps is designed for an experienced apprentice or journeyman who seeks to learn more detail on the operation of heat pumps. The book, published by Delmar Cengage Learning, emphasizes the service technician’s perspective and progresses from the refrigeration cycle to more in-depth topics.

No, the U.S. military hasn’t abandoned its oh-so-familiar Army Jeep green. Though, these days, the words silver, gold, and platinum have forcefully worked their way into Army vocabulary and color scheme.
