Which components maintain the high and low pressures in an absorption refrigeration system?

In an absorption refrigeration system, the components that maintain the high and low pressures are the generator, absorber, and solution pump.

The generator's role is to heat the refrigerant solution, allowing it to separate into vapor and liquid. This process creates the high-pressure vapor needed for the refrigeration cycle. The absorber, on the other hand, is where the vapor combines with the refrigerant solution, resulting in a low-pressure condition as the vapor dissipates back into a liquid. The solution pump circulates this liquid refrigerant back to the generator, ensuring a continuous flow and maintaining the pressure dynamics of the system.

Together, these components are crucial in establishing and regulating the pressure necessary for effective refrigeration and heat exchange within the system. Understanding how these elements interact helps clarify the overall operation of absorption refrigeration systems. Other options do not encompass these critical pressure-maintaining components effectively.
