Energy efficiency, the growing popularity of ductless and variable refrigerant flow (VRF), the evolution of heat pumps into whole-home solutions, and the Internet of Things (IoT) are a few of the major trends influencing products in the residential air conditioning market.
Bristol Compressors Intl., LLC, a producer of compressors for use in air conditioning, heat pump, and refrigeration systems, announces the addition of Luka Lojk to its senior management team as vice president of sales and marketing.
Bob and Tim are on a service call on a really cold and blustery day. The temperature is 27°F, the wind is blowing, and it’s snowing and sleeting. When the customer called, she said that their home is getting cool inside, and their heat pump is running all the time with the temperature dropping inside the house. They arrived at the front door, talked to the homeowner, and decided to look around. They went to the closet where the indoor unit for the heat pump was located and determined that the heat pump itself was not running, only the fan and strip heat.
These four-way reversing valves cover 93- and 119-ton applications and are suitable for 1- to 119-ton cooling capacities. They allow heat pump systems to switch between cooling and heating modes by changing the flow path of the refrigerant.
Finland system uses waste energy from computing center to heat 1,500 homes
September 5, 2016
A groundbreaking district heating scheme in Finland has harnessed waste heat generated by a computer center to heat homes. The project uses an advanced heat pump system based on high-performance Bitzer compressors.
The HRC Series’ two-piece chassis is housed in an attractive cabinet with a durable powder-coat finish. A 5-inch sub-base and a louvered grille are available as options. Unit controls include advanced digital changeover between heating and cooling along with fan speed selection.
Xergy Inc. has announced a new refrigeration system based on an electrochemical compressor to replace the conventional mechanical vapor compression systems found in typical heat pumps. The company credits the University of Delaware’s Ajay Prasad and his research team with playing an important role in the breakthrough.
The LX Series heat pump has the ability to adjust its operating capacity and provides quiet, efficient operation as it adjusts heating and cooling levels up or down to provide only what is needed to condition the space.
