What can excessive load on the evaporator lead to?

Excessive load on the evaporator can lead to reduced compressor efficiency. When the evaporator is overloaded, it can experience a situation where the incoming refrigerant is not able to absorb enough heat. As a result, the refrigerant may not fully vaporize, leading to a higher liquid level in the evaporator. This condition can cause the compressor to work harder to maintain the required pressure and temperature levels, which ultimately reduces its efficiency.

When a compressor operates under increased load without receiving adequate heat absorption from the evaporator, it may overheat and strain its components, leading to wear and tear or even potential failure. Therefore, maintaining the proper load on the evaporator is essential for the efficient operation of the entire air conditioning system.
