When the three-way valve is closed (A-AB) the secondary pump delivers the thermooil through the secondary flow pipe, through the air-heat exchanger, the secondary return pipe and through the secondary bypass. When the three-way valve opens a little bit (A-AB), some thermooil will inject from the primary main flow pipe to the secondary flow pipe. Simultaneously, the same quantity of thermooil leaves the secondary circuit over the three-way valve back to the primary main return circuit. The secondary circuit is always self-contained and so we do have two circuits with two different quantities of thermooil and now we are able to work with two different temperatures. For example we do have 230°C/ 200°C (DT 30) in the primary main circuit and 180°C/ 170°C (DT 10) in the secondary circuit.

Constant transporting capacity with exact air temperature

Cost-effective construction

Conclusions

The controller controls the three-way regulation valve (mounted in the main return pipe), dependent on the measured air temperature. According to the necessary requirement of energy the thermooil goes through the air-heat exchanger, through the three-way regulation valve (A-AB) and back to the main return pipe. The quantity of oil which is not used in the air-heat exchanger goes through the bypass and through the three-way regulation valve (B-AB) also back to the main return pipe. The inlet temperature at the air-heat exchanger is always the highest temperature from the main flow pipe. The temperature difference (D T) over the air-heat exchanger can be very big (less thermooil).

Variable quantity of thermooil with less exact air temperature
