Frequently Asked Questions
Why are refrigeration compressors sized for 16 to 18 hours of daily run time?
Evaporator cooling coils in cold storage operate below freezing and continuously accumulate frost from infiltrating humidity. Systems require 4 to 6 hours each day for scheduled automatic defrost cycles (hot-gas or electric defrost) and post-defrost temperature pull-down, requiring the entire daily heat load to be satisfied in 18 operating hours.
What is frost heave and how is it prevented in sub-zero freezers?
Because ground soil under an unheated freezer slab remains in constant contact with sub-zero temperatures, freezing temperatures penetrate deep into the earth. Sub-surface ground moisture freezes into ice lenses that expand with immense pressure, buckling concrete slabs and cracking structural building columns. Prevented by installing glycol heating loops or electric heating grids under insulation.
What makes up the largest refrigeration load in a cold storage warehouse?
For high-turnover logistics warehouses, infiltration from dock door openings and product pulldown heat often account for 50% to 65% of total refrigeration load, while static envelope panel transmission typically accounts for 25% to 35%.
