Caution must be used when near the top of the Scroll compressor.
Operating temperatures can be high enough to cause serious Injury.
brazed copper and stainless steel design. Refrigerant and liquid solution is channeled
through narrow openings between plates and flows in opposite directions. The
counter flow design and fluid turbulence ensures maximum heat exchange at minim
pressure drop.
Reversing Valve:
The four (4) way reversing valve when installed in the
Multiaqua Heat Pump Chiller (MACH), reverses t h e direction of refrigerant flow
through the heat exchanger and outdoor coil to provide heating and cooling from
the system and to provide for defrosting of the outdoor coil during low ambient
conditions.

Bi-Directional Expansion/Check Valve:
Multiaqua heat pump chillers are
equipped with Thermostatic Expansion/Check Valve combination. The valves
feature a liquid charged sensing bulb for constant superheat at various load
conditions during the heat and cool mode of chiller operation. During the reverse
cycle the internal check valve opens to allow refrigerant to flow through the valve
with no pressure drop through the check valve.
Suction Accumulator:
The suction accumulator is used to prevent excessive quantities of
liquid refrigerant and oil from returning to the compressor during normal operation.
