Air can heat pump working principle and its application

For energy use, can from the two aspects to consider the quantity and quality. Both should attach great importance to the utilization of energy, and attention in the use of appropriate grade, lest cause inappropriate energy value. According to some industrial developed country series juice, less than 100 ℃ heat consumption accounts for about more than a third of the total energy consumption. Civil heat supply is generally used the high grade of energy, its smoke loss is too big, very reasonable. On the other hand, the industry has a large number of low temperature waste heat, rivers and lakes, atmosphere, ocean contains a large amount of thermal energy, if it with the method of artificial potential temperature increase, and will save a lot of energy.

Heat pump is part and parcel to input can high quality or high temperature heat energy at the expense of, through the thermodynamic cycle, heat transfer by low temperature object to high temperature object, for heating or other technological process of hot - kind of equipment.

In thermodynamics, the working medium after '- series of state changes and return to the original state of the process is called circulation process, or simply the loop. Using the state of the working medium, the heat energy into mechanical energy cycle is called positive cycle, all of the heat engine are in accordance with this kind of circulation work. Through changing the state of the working medium, the heat from low temperature object to high temperature cycle is called reverse circulation, the refrigeration cycle and the heat pump cycle is belong to reverse circulation.

L air heat pump

Air compression type heat pump as shown in figure 6-6-1, it is the use of gas as working medium, the air in the cold storage room, due to the reduced pressure, the temperature drop, heat absorption of low temperature heat sent after, be compressor compression pressure and temperature, and then in cooler cooling heat. In principle, in between the two heat source heat pump works, as shown in figure 6-6-2, consumes power W, in low temperature heat sources of heat supply QI, high temperature heat source for heat Q1

Can be seen from the above several formulas, coefficient of work and the size of the two heat source temperature has a direct relationship.
