Resources: Oak Ridge national Laboratory The population of the desert city Las Vegas has soared by over 30% in the past decade, a trend that has severely strained local electrical companies in terms of finding water to run through their cooling towers. (Contrary to popular belief, Las Vegas does not get all or even most of its electricity from the Hoover Dam. Most of that power…

In order to evaluate and improve the performance of a ground-coupled heat pump (GCHP) heating system with radiant floors as terminals, an exergy analysis based on test results is performed in this study. The system is divided into four subsystems, and the exergy loss and exergy efficiency of each subsystem are calculated using the expressions derived based on exergy balance…

Yes, you should clean it. Or better, have a professional clean it. Watch how they do it, and take notes. Then next time, you can clean it yourself. The technician may take the cover off the unit, and spray from the inside out. If you re going to do it yourself, check the manufacturer s documentation for the approved cleaning method. It usually involves gently rinsing it with…

Operation of a Carnot refrigerator For a Carnot cycle we know the ratios of heat in to heat out when the cycle is run forward and, since the cycle is reversible, these ratios are the same when the cycle is run in reverse. The coefficient of performance is thus given in terms of the absolute temperatures as This can be much larger than unity. The Carnot cycles that have been…

Hybrid heat pump water heaters are a new, highly efficient way to heat water. They typically cost half as much to operate as traditional electric resistance water heaters, and can save a homeowner as much as $2, 500 over the lifetime of the unit. While they heat water, heat pump water heaters also air condition and dehumidify the space around them. To understand the concept…

The higher the outlet temperature of the heat pump, the more work the compressor has to do to achieve this temperature. Therefore the more power the heat pump requires and the lower COP. The temperature leaving the heat pump will actually be less than this ‘compressor off’ temperature due to loses across the heat exchanger within the heat pump. This graph gives an indication…

Heat pumps are potentially the most efficient type of electric heat. When heat pumps properly installed, heat pumps can deliver 1 1/2 to 3 times more heat energy to a home than the electric energy they consume. Unfortunately, the energy savings produced by the heat pump’s design are often lost to poor installation and neglected maintenance. All heat pumps include two different…

For climates with moderate heating and cooling needs, heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator, heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm…

Heat pumps are systems that transfer heat energy from a lower temperature to a higher temperature (hot source), by inverting the natural thermal flow (in which heat is carried from warm mediums towards cooler ones). This flow capability works whether one wishes to provide heating or cooling with a single piece of equipment. In heating mode, the system supplies the room heat…

Heat pump technologies include phase change, thermoelectrics, thermoacoustic and magnetic coolers. HVAC and other phase change cooling methods are mechanical in nature. Phase change works by using a volatile gas (a refrigerant) that is mechanically compressed to a liquid with low energy and then pumped through a loop. The refrigerant is evaporated on a heat source, absorbing…

What’s the best heating system to have for cold snaps: my standard A/C system with heating or should I look into investing in a heat pump? The best heating system for a Florida home always depends on how chilly it gets where you live and how warm you like to keep your home when it gets cold outside. A/C systems with heat strips Most Florida homes, like yours, have a straight…

Being so close to the beach, we don’t like to think about winter very much. But, it does cool down here in Freeport, TX even if we don’t like to think about it, but many people have a great system for both heating and cooling their homes: a heat pump. However, there can be some concern over whether a heat pump in Freeport, TX is sufficient for winter weather. Where does the…

An air source heat pump (ASHP) is a system which transfers heat from outside to inside a building, or vice versa. Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another. They can be used as a space heater or cooler, and are sometimes called “reverse-cycle…

The Heat Pump is very simple once you understand the basic concept (and I promise you will after reading this). As the name suggests a heat-pump transfers or pumps heat from one place to another, (notice the use of the word “pump”- heat is not generated but rather is moved). As they say “a picture worth a thousand words”. So let’s see one: In this Example: The flame heats up…

(NAPS)—When a new heating system is in your home’s future, you’d be wise to consider the pros and cons of heat pumps and furnaces. Both distribute air through a home using heated air rather than heated water. A heat pump does this by extracting heat from outside air and circulating it through your home. A furnace uses electricity or gas to produce heat. The following tips can…

Recently I ve learned of two people running their heat pump in a way that costs them a lot of extra money. With heat pumps, there s an extra setting on the thermostat. In addition to heat, cool, and off, there s a setting for emergency heat. But what is that setting for? What does it do? A heat pump, as I wrote before, pulls heat from the outside air (unless you have a ground…

The ground absorbs nearly half of the solar energy our planet receives. As a result, the earth remains at a constant, moderate temperature just below its surface all year round. However, air temperature varies greatly from summer to winter, making air source (traditional) heating and cooling least efficient when you need it the most. Geothermal heating and cooling systems take…

Heat pumps can provide cost-effective and energy-efficient heating, cooling and water heating for homes and businesses. While traditional systems burn fuel to create heat, a heat pump instead works by moving heat into or out of a building. Though they require electricity to operate, efficient heat pumps can provide the same amount of heating for a third of the electricity needed…
