1. Types of Heat Pumps Bryan Vandenberg OBJECTIVE: present the common heat pump types and illustrate their applications

2. Phase Change Heat Pump Most Common –Used in refrigerators and air conditions Compressor –PV=nRT Condensor –Heat is removed Refridgerant Metering Device –Causes liquid to cool Evaporator –Collects heat from container Gas –CFC, Freon - 1,1,1,2 -tetraflouroethane

3. Geothermal Heat Pump aka: Ground source heat pump Components –Compressor, pipe loop, pump 2000 m² home –1200 m vertical pipe –1600 m horizontal pipe $ 5000 – 1300 initial cost

4. Thermo Electric Heat Pumps Peltier – Seebeck effect: thedirect conversion of electricity into heat differentials Seebeck – temperature  voltage Peltier – voltage  tempeature gradient Low initial cost, high operational cost
