How are heat pumps so efficient? Seriously, how do heat pumps work when it's cold outside? Three rules to (mostly) explain why heat pumps work Heat pump parts and what they do Tying it together: The refrigeration cycle More on heat pumps and clean energy A heat pump is a su...
Heat exchangers have lots of other familiar uses too. Engines in cars, ships, and planes use heat exchangers to work more efficiently, gas boilers use them to heat up hot water, and if you have a refrigerator or an air-conditioner in your home, those are using heat exchangers too. So ...

Using this calculator, everybody can roughly estimate what size heat pump they need. This is primarily a mini-split heat pump size calculator but can be used to roughly estimate the size of ground-source or even water-source heat pumps. The heat pump size calculator outputs the resulting size...
water flows in heaters and coolers should be reduced in relation to the air volume. This will maintain control and avoid unnecessary pump work. Furthermore, in systems with intelligent con-trol [6] it is possible to automatically optimise media flows on both sides of the heat exchanger with ...
Unplug the swamp cooler andadjust the float armif the water isn't at the proper level. A swamp cooler only works effectively when the water level is high enough to keep the internal pads damp. If the pads start to dry out, the swamp cooler may not work on the high setting. ...
Essentially, several units (control panel, pump, solar collector etc.) work in sync to collect the sun's light and heat the water. It has smart sensors: one is temperature sensitive detecting whether the water is hot; the other is "flow" sensitive, alerting the unit when hot water is be...
It does not matter where the pressure tank is on the water system and I saw examples where the tank was installed off to the side. To make the new placement of the tee work I had to cut back the existing pex and install an exact amount of pipe connection to make it leak proof. I...
Peering down into the hole, I saw a cord plugged into the wall and realized I was looking at the back of the refrigerator. So not only did this hole in the ceiling allow a lot of warm air from the house to leak into the attic, but it got an assist with the extra heat from the...
How much work did this take, in Btu? The general heat pump uses 17-kJ of work while rejecting 40-kJ of heat to the hot reservoir. How much heat (in kJ) does the heat pump receive from the cold reservoir? A heater is used to take a saturated mixture of water a...
