38UQZ-40ALZ Split System Air to Air Heat Pump

Brief Description:

This system consists of seven sizes with nominal cooling capacities from 18.7 to 67.0 kW and nominal heating capacities from 20.8 to 78.4 kW.
It is a split-system heat pump for cooling only and heating applications, consisting of remote air-cooled outdoor units 38UQZ and 40ALZ indoor units.

 
 
 
 
  • Seven sizes with nominal cooling capacities from 18.7 to 67.0 kW and nominal heating capacities from 20.8 to 78.4 kW.
  • Split-system heat pumps for cooling only and heat pump applications, consisting of remote air-cooled outdoor units 38UQZ and 40ALZ indoor units.
  • Refrigerant lines (gas and liquid) and electrical cables connect the two units.
  • Three-phase hermetic reciprocating compressors, operating on R-407C refrigerant, and including a crankcase heater.
  • Refrigerant-to-air heat exchangers (evaporators and condensers), made of copper tubes and pre-treated water-resistant aluminium fins.
  • All-copper refrigerant circuit. Indoor unit refrigerant control using thermostatic expansion valves, with bypass using non-return valves.
  • 38UQZ units use throttle valves for the expansion in heat pump mode.
  • High and low pressure switches and filter drier, outdoor fan control high pressure switch (38UQZ 014).
  • Complete internal wiring. Thermal-magnetic disconnect switches for compressors and fan motors.
  • The indoor units have centrifugal fans driven by three-phase motors with adjustable belt-pulley drives. The outdoor units have direct-drive propeller fans.
  • Pre-painted galvanised sheet steel casings, thermal and acoustical insulation. Flexible shock absorbers.
  • Unit connections to Carrier Comfort Zone II, VVT and TEMP systems (depending on the model).
  • Defrost control, anti-liquid slugging tank, discharge line muffler and thermal protection.
    Optional Accessories
  • Electric resistance heaters or hot-water coils for 40ALZ indoor units (option/accessory)
  • Low refrigerant pressure switch for 38UQZ outdoor units (option)
  • Outdoor air thermostat for connection to the supplementary heating coil for units (38UQZ/40ALZ 007, 008 - option/ accessory)
  • Head pressure control for cooling operation at outdoor air temperatures below +19°C (38UQZ - option/accessory)
  • Special drives for higher indoor unit fan static pressure (40ALZ - option)
  • Room thermostat, wired remote control -versions: 220 V for sizes 38UQZ/40ALZ 007 and 008 (accessory)
  • 24 V for sizes 38UQZ/ALZ 011 and 014 (programmable, with remote sensor option for return air duct or room air, or non programmable - accessory)
