(2)Compressor overlapping run
When unit cannot maintain cooling performance with a single compressor, compressor running time
overlaps between Compressor A and B.
a) When unit reaches set temp -0.4㷄during compressor overlapping run, either Compressor A or B
stops running.
When unit reaches set temp -0.4㷄for the 1
st
time during compressor overlapping run, Compressor B
stops running. When a unit reaches set temp -0.4㷄for the next cycle during compressor overlapping
run, Compressor A stops running.
b) When unit cannot maintain cooling performance with a single compressor and reaches set temp
+0.4㷄, the stopped compressor will run. (Compressor overlapping run)
c) When unit reaches to set temp -1.5㷄 in compressor overlapping run, either Compressor A or B stops
running. (Compressor alternate run)
Operation sequence of Compressor overlapping run
㽹 Turn on both Compressor A and B. (Point 㽹 in the picture below)
㽺 When unit reaches set temp -0.4㷄during compressor overlapping run, Compressor B stops
running. (Point 㽺 in the picture below)
㽻 When unit reaches set temp +0.4㷄 within 90 minutes, Compressor B will start running.
(Point 㽻 in the picture below)
㽼 When unit reaches set temp -1.5㷄 in compressor overlapping run, Compressor A stops running.
