Direct exchange Direct exchange geothermal heat pump The Direct exchange geothermal heat pump is the oldest type of geothermal heat pump technology. It is also the simplest and easiest to understand. The ground-coupling is achieved through a single loop circulating refrigerant in direct thermal contact with the ground (as opposed to a combination of a refrigerant loop and a water loop). The refrigerant leaves the heat pump appliance cabinet‚ circulates through a loop of copper tube buried

SOLAR BOOSTED HEAT PUMP WATER HEATERS ABSTRACT This paper presents an overview of the solar boosted heat pump water heater technology. The tests made on direct expansion solar assisted heat pumps have shown that good COP can be attained while using working fluids that do not cause any harm to the environ ment. Modifications to the condenser in the heat pump can be made in order to improve and distribute evenly the heat transferred to the water. NOMENCLATURE HPWH – Heat Pump Water Heater SBHPWH

Technology in Practice Part II: Intra-Aortic Balloon Pump Background of Technology Before tThe intra-aortic balloon pump (IABP) became a successful piece of technology‚ it was first introduced by Harken in 1958 in hopes of treating left heart failure (IABPumpers‚ 2006). Harken thought that by removing a certain amount of blood from both femoral arteries during systole‚ and rapidly replacing it during diastole‚ he could augment the cardiac output and increase coronary perfusion. However

financial impact on CJI. One of the parts‚ a bilge pump‚ was an item that CJI had been purchasing from one of their suppliers‚ Heavey Pumps‚ a small local specialty pump manufacturer‚ on an informal‚ noncontract basis. The remaining items were all built in-house by CJI and supplied to Great Lakes from one of their two finished goods warehouses located near the Great Lakes production facilities. Heavey Pumps was producing and delivering 50 bilge pumps at a time at a cost of $1‚500 per unit and built
