The higher the inlet water temperature, the more sensible heat must be removed from the water and the longer the freeze cycle. The latent heat removed causes the water to change state, thus producing ice.
There are many reasons why some choose to work unsafely, but a big one is just being lazy. Try to avoid this and always take the extra time needed to work safely.
It is always best to find and repair the source of the leak. But depending on the size of the system and the size and location of the refrigerant leak, it may not be an easy or inexpensive repair.
Here is the potential problem: A contractor quotes a customer on the compressor replacement, and he agrees to repair the cooler at the quoted price. Then, as the technician is completing the job — or even after he has finished replacing the compressor — he finds out there is another system problem.
While troubleshooting and repairing refrigeration systems, a common problem is a starved evaporator, meaning not enough refrigerant is entering the evaporator for the heat load placed on it.
Many single-phase compressors require a start capacitor to assist in starting the motor. These capacitors will occasionally fail, causing a compressor to fail to start.
When replacing electrical components, it is very important to ensure the component is properly grounded. Do not overlook the importance of the ground wire. Although many times an ungrounded component will not affect the operation, it is not safe.
