| Popis: | A heat pump in the most basic sense, is little more than a conventional air – conditioning system that is equipped with the necessary components to cause it to reverse its running cycle, while the heat pump is operating in reverse, it absorbs heat from the air outside and releases it inside the building. In this system Freon gas (R134) was used because it is more efficiency from the other kinds of gases that used for conditioning, and the data that produced from this system at its running time was compared with that produced from another system also used the same kind of gas. In this work the first step is to measure the temperatures at various points in the cycle (t1-----t8) these points are: •The temperature of (R134) at outlet from the compressor. •The temperature of (R134) at outlet from the condenser. •The temperature of (R134) at outlet from the expansion valve. •The temperature of (R134) at outlet from the evaporator. •The temperature of water at inlet to the condenser. |
