The difference between single cycle and double cycle

The difference between single cycle and double cycle lies in the different control methods of evaporator and compartment.

A cycle is an evaporator. No matter which room's refrigeration will eventually be transferred to another room for refrigeration, the temperature is too low, and the room that needs refrigeration can't reach the ideal temperature for a long time because of insufficient refrigeration capacity, and the refrigeration effect is not good.

However, the double cycle is two evaporators. The electromagnetic valve determines that the flow direction of refrigerant is controlled by two controlled room thermostats, and the rooms are independent of each other and do not interfere with each other, thus realizing independent refrigeration between rooms, with more accurate temperature control, more concentrated refrigeration capacity, faster refrigeration speed and better refrigeration effect. Double circulation is more expensive than single circulation because the fresh-keeping effect will be better, and there will be no odor, because single circulation transfers cold air from the freezing room to the refrigerating room, while double circulation is independently cooled by thermostat.

Cyclic sentence making

1. According to the principle of system power cycle and the characteristics of Freon cycle power generation system, a small-scale low-temperature waste heat power generation system model is established, and the evaporator, condenser, steam turbine model and other components are designed.

2. Even so, its recovery stress still has good thermal cycle stability under the excitation of large constant current, which can meet the needs of emergency repair of civil engineering damage.

3. Similarly, the occurrence of floods and droughts is a direct manifestation of carbon cycle problems. When soil is squeezed or eroded, rainwater will evaporate and run off.

4. The high-tech flower shed located on the other side of the shed area is relatively less affected by the weather, because the internal circulation heating system in the shed can increase the temperature in the shed and prevent the flowers from rotting by creating internal circulation airflow.

5. Kramer calculated that in Haiti, if half of human excrement can be recycled and made into fertilizer for agriculture, the agricultural input will rise to per hectare 17 kg of nitrogen fertilizer.
