상품 소개

Liquid refrigerant enters a brass distributor and divides through small feeder tubes into multiple copper circuits. It evaporates as air crosses the fin pack, then returns through a large suction header to the remote condensing unit. Distributor sizing, circuit length and coil orientation are coordinated to keep all rows active across the expected load range and to return oil reliably.

주요 기능

A precision distributor divides two-phase refrigerant among equalized evaporator circuits.

Copper circuits and aluminum fins provide direct sensible and latent cooling without a secondary water loop.

A large suction header collects vapor at controlled velocity for stable superheat and oil return.

Independent or intertwined circuits can support staged compressors and part-load face coverage.

고객 제품 관심사

DX coils depend on uniform refrigerant distribution and correctly matched circuits to prevent starving, flooding and temperature streaks.

Unequal feeder flow leaves some coil circuits inactive.A matched distributor and equal-length feeder tubes divide refrigerant across every circuit.

Low load causes unstable superheat and liquid carryover.Staged or intertwined circuits preserve active face area and stable expansion-valve control.

Long suction runs fail to return compressor oil.Header diameter, circuit velocity and piping traps are selected around the remote condensing unit.

Condensate carryover wets downstream filters.Coil face velocity, fin treatment and drain-pan geometry are coordinated for complete drainage.
