How an Insulin Pump Works The device releases insulin almost the way your body naturally does: a steady flow throughout the day and night, called basal insulin, and an extra dose at mealtime, called a bolus, to handle rising blood sugar from the food you eat. You program the pump for ...

Pump it up: a look at how a heat pump works, what it can do and tips on how to install it.(Technically Speaking)Owenson, Peter
As the pool pump circulates the swimming pool's water, the water drawn from the pool passes through a filter and the heat pump heater. The heat pump heater has a fan that draws in the outside air and directs it over the evaporator coil. Liquid refrigerant within the evaporator coil abso...
As the pit fills with water, the pump turns on. It moves the liquid out of the pit through pipes that run away from your home to a spot where the water can drain away from your foundation. The pipe usually has a one-way valve called a check valve at the pump end to keep the ...
Here’s a step-by-step process of how heat pumps work: Heat could be sourced from the air outside or warmth from the ground. This is blown or pumped over the heat exchange surface of the exterior part of the heat pump. This heat is warm enough to cause the refrigerant liquid in the...
In heating mode, the heat pump works as follows: heat from the earth connection arrives at an earth connection-to-refrigerant heat exchanger called the evaporator (see Figure 2). On the other side of the heat exchanger is cold refrigerant in a mostly liquid state. The refrigerant is colder ...
When it comes to cooling, a heat pump works in basically the same way as a traditional A/C: Refrigerant liquid absorbs heat from indoors Compressor cycles refrigerant to the outdoor fan Spinning of outdoor fan cools the refrigerant Refrigerant releases heat outside Compressor cycles cooled refrige...
How? They fiddle with the pressure of the refrigerant, forcing it to switch between liquid and gas forms at just the right times. A heat pump uses 60 to 70 percent less energy to heat your home than a traditional heating system like a furnace, boiler, electric radiator, or wood stove. ...
