Advantages and Benefits
of
Top Mount Condensing Units
vs
Bottom Mount Condensing Units |
| |
Bottom Mount Reach-in's Have a Far Greater Potential for Trash, Dirt and Debris to be Swept
Directly onto the Floor Level Condenser Coil and Condenser Fan. This Increased Exposure to Dirt
Will Cause Probable Premature Condenser Blockage and the Definite need for More Frequent
Condenser Cleaning and Required Fan Service. |
Top Mount Reach-in's are Exposed to Airborne Dirt, thus, Minimizing the Chance of
Condenser Blockage and they Require Far Less Frequent Condenser Cleaning and Fan
Maintenance. |
| |
Bottom Mount Reach-in Condensing Units are Much More Difficult to Access and Service than
Top Mount Models since the Compressor, its Fittings and the Cabinet Electrical Control Panel
can Only be Accessed on Hands and Knees. Also, Compressor Replacement is Extremely Difficult
on Bottom Mount Condensing Units since it is Awkward to Unbolt, Un-Braze and Remove the
Compressor with the Case Bottom Clearance Limitation. |
| |
Compressor Heat of a Bottom Mount Reach-in is Rejected through Conduction, Directly to its
Case Bottom, thus, Requiring Greater Insulation and/or an Increased Horse Power Condensing Unit
to Combat the Heat Load Transfer to the Interior Floor of the Cabinet. This Equates in a Loss since
More Energy is Required to Operate a Bottom Mount Reach-in because of its Nature to Reduce its
own Capacity from an Increased Heat Load. |
Top Mount Reach-in's Do Not have these Losses since the Heat is Dissipated
in the Air Above the Condensing Unit. |
| |
On a Bottom Mount Reach-in, the Useable Interior Upper Space is Greatly Reduced, Lost or out of
Reach, since the Condensing Unit Compartment is Knee high. |
Top Mount Reach-in's Useable Interior Space Starts at a Convenient Low Height and Continues to
a Reachable Top Height. |
| |
Bottom Mount Reach-in's Demand Use of Longer and Obtrusive Refrigerant Liquid/Suction Lines to
Connect the Bottom Condensing Unit to the Interior Top Evaporator Coil. Capacity of the Condensing
Unit is Decreased and Lost Due to the Lengthy Refrigerant Lines. |
Top Mount Reach-in's use Short Refrigerant Liquid/Suction Lines to Connect the Condensing
Unit to the Interior Top Evaporator Coil, and Capacity of the Condensing Unit is Increased
Due to the Short refrigerant Lines. |
| |
Accessibility of the Refrigerant Lines and Evaporator Fan Wiring of a Bottom Mount Condensing
Unit for Servicing is Limited since the Lines and Wiring must be either Concealed in the Interior
with an Obtrusive Cover or Foamed in Place and Not Serviceable or Accessible at all. |
Accessibility of the Refrigerant Lines and Evaporator Fan Wiring of a Top Mount Condensing Unit
for Servicing is Very Easy since the Lines and Wiring are Fully Exposed and Easily Accessible. |
