System's response to changes in load or ambient temperature can be predicted by the operating characteristics of the cap tubes presentea in the previous sections. To illustrate the system's response to load changes or condensation, average, let's start with the operating system in stationary conditions. If the amount of heat entering the conditioned space increases, evaporators temperature increases, and the system enters the transition period of the answer. Over a period of time after the evaporator load increases, the rate of refrigerant mass flow through the tube cover remains constant. Additional heat entering the space produces a corresponding increase die superheat steam entering the compressor.
This higher level of overheating increases the heat of compression and saturated pressure of condensation of the refrigerant. As the condensing pressure increases, this leads to the rate of refrigerant flowing through the tube cover to increase. Increase the amount of proceeding of the refrigerant in the evaporator produces a corresponding increase in the pressure in the evaporator.
This response reduces the heat of compression and differential pressure in a tube cover. The system remains in transition as it tries to create a new point of balance between the flow rates through the compressor and tube cover.
At the same time, as a stream through the tube cover stabilize at a new rate, the higher the temperature of condensation of reducing the amount of refrigerant hypothermia. Reduction of hypothermia increases flashes occurring in the cap of the tube, thus decreasing the flow of the refrigerant in the evaporator. The net effect of these two reactions is that the system reaches equilibrium during the work in the evaporator higher the temperature and pressure than it was before the load changes happened. The system remains in the new state until the changes in the evaporator load or condensing temperature of the environment occurs. If the evaporator load is reduced suction superheat, heat compression, condenser pressure, temperature, condensation and reducing the pressure in the evaporator. These reactions in your system to achieve a new operating point of equilibrium at low evaporator pressure and temperature...
