Some of the factors that affect conversion of sound

power to sound pressure and consequent NC level include:
• Acoustical ceiling type
• Use of metal or flex duct
• Absorption in the occupied space
• Location in the occupied space
• Open or closed layout plan
• Use of open or ducted returns
• Orientation of unit to occupant
• Use of lined or unlined duct

ASSOCIATED WITH NC CURVES

WSHP sound control

Analyzing the projected sound level in the conditioned
space caused by a WSHP unit is quite involved. The key is
to have good sound power ratings (Lw) in dB on the equip-
ment to determine the ductwork, ceiling and room sound
attenuation effect. We provide suggestions for console unit
sound design around the WSHP units.

Console units

With console units, the fan and compressor are located
within the space, and only the casing design attenuates the
transmission of sound sources into the space. The designer
should carefully review the manufacturer’s acoustical data
when selecting console units and use lower fan speeds to
minimize space noise.

Operating limits

Environment

This equipment is designed for indoor installation ONLY.

Power supply

A voltage variation of ± 10% of nameplate utilization volt-
age is acceptable.

Starting conditions

50KQA units

The 50KQA units start and operate in an ambient temper-
ature of 40 F, with entering air temperature at 40 F, with
entering water temperature at 70 F, with both air and
water at the flow rate used in the ARI Standard 320-86
rating test, for initial start-up in winter.

50KQD units

The 50KQD unit will start and operate in an ambient tem-
perature of 40 F, with entering air temperature at 40 F,
with entering water temperature at 40 F, with both air and
water at the flow rates used in the ARI Standard 320-86
rating test, for initial start-up in winter.
NOTE: These are not normal or continuous operating
conditions. We assume that such a start-up is used to bring
the building space up to occupancy temperature.

AIR LIMITS

WATER LIMITS

    LEGEND

NOTES:

1. Minimum Air and Water conditions can only be used at ARI flow

rates.

2. Only one maximum or minimum value may be used with 50KQA

units, all other parameters must be at normal conditions. The
50KQA units may have up two values at maximum or minimum
with all other parameters at normal conditions.

Solenoid valves

In applications using variable flow pumping, solenoid
valves can be factory installed and operated from the con-
trol board in the Aquazone™ WSHP unit.

Freeze protection

Applications where systems are exposed to outdoor
temperatures below freezing (32 F) must be protected from
freezing. The most common method of protecting water
systems from freezing is adding glycol concentrations into
the water. Use design care when selecting both the type
and concentrations of glycol due to the following:
• Equipment and performance may suffer with high con-

centrations of glycol and other antifreeze solutions

• Loss of piping pressure may increase greatly, resulting

in higher pumping costs

• Higher mixture viscosity may cause excess corrosion

and wear on the entire system

• The water’s acidity may be greatly increased, promoting

corrosion

Glycol promotes galvanic corrosion in systems of dissimilar
metals. The result is corrosion of one metal by the other,
causing leaks.
