What is a coaxial heat exchanger? A coaxial heat exchanger is a kind kind of tube heat exchanger, it is usually used as condenser or evaporator  in a heat pump, marine air conditioner, swimming pool, water chiller etc. Mostly it is a water cold heat exchanger. The structure can be as round, rectangle, spiral, double helix and so on. The structure of coaxial heat exchanger The coaxial heat exchanger is designed as a "tube in tube" structure. Usually the outer tube is made of steel/copper, and the inner tube can be titanium, copper, copper-nickel depending on the requirements of working condition.  For the inner tube is has many spiral grooves on the surface, which will enlarge the connection surface and get more heat transferred. How does the heat exchange in the coaxial heat exchanger? Mostly water flow  in the inner tube and refrigeration flow between the outer & inner tube(refrigeration loop). The temperature of refrigeration and water are different

A pool heat pump uses electricity to operate and also uses the sun-warmed air which contributes to the efficiency of the unit. Heat Pump Pool Heaters use electricity and do not generate heat. As the pool pump circulates the swimming pool water, the water drawn from the pool passes through a filter and the heat pump water heater. The heat pump heater has a fan that draws in the outside air and circulates air through an outer evaporator air coil. Liquid refrigerant within the evaporator coil absorbs the heat from the outside air and transforms it into a gas. The warm gas in the coil then passes through the compressor. The compressor increases the heat, creating a very hot gas that then passes through the coaxial heat exchanger condenser. As the gas and pool water is pumped through the coaxial heat exchanger, the hot gas transfers its heat to the water.  The water is heated 3-5 degrees as it circulates through and then warmer water flows back into the pool.  The hot gas,

Work in the reverse way of air conditioner Geothermal Source  heat pump is also a kind of air conditioner , and it transfer heat from water to house . We know the air conditioner in our house it absorb the heat in our room and release it outside, and thus makes the room temperature decline. Comparing with our home air conditioner The Geothermal Source heat pump works in the reverse way. It absorb the heat in the ground water or other water and transfer it to house to heat water or air in the room.     What is a Geothermal Source heat pump consist of? Before we talk about the principles of Geothermal Source heat pump we have learn the components of a Geothermal Source heat pump.Usually it consists of three components: 1.  H eat source system 2.  H eat pump 3.  H eat distribution and storage system Geothermal Source Heat pump cycle Geothermal Source heat pump cycle is usually vapor-compression cycle  the same as most other heat pumps.
