ment is provided.

APPLICATIONS
Unitized Energy Recovery Ventilators (UERV) are used with
the York rooftop packaged units. The internal wheel provides
sensible and latent energy exchange between the entering
and exhaust air streams of a building. This allows a substan-
tial amount of the energy, which is normally lost in the
exhaust air stream to be returned into the entering air. Ideal
applications are areas that have cold or hot temperatures, or
areas that have high humidity or very low humidity (recover
exhaust air from buildings that have humidifiers to add
humidity). Application software is available to provide the
energy and dollar savings for all areas of the United States
and Canada.
PRINCIPLE OF OPERATION
The UERV enthalpy wheel contains parallel layers of a poly-
meric material that are impregnated with silica gel (desic-
cant). The wheel is located in the entering (intake) air and
exhaust air streams of the ventilation equipment. As the
wheel rotates through each air stream, the wheel surface
adsorbs sensible and latent energy. In the heating mode, the
wheel rotates to provide a constant transfer of heat from the
exhaust air stream to the colder intake air stream. During the
cooling season, the process is reversed. On units equipped
with an economizer (3 - 12.5 tons), the wheel pivots out of the
air stream to allow economizer to operate normally for "free
cooling" when outdoor temperature and humidity is accept-
able. During economizer operation, the UERV exhaust
blower continues to run, providing power exhaust for the sys-
tem. The intake blower is de-energized during economizer
operation.
ARI STANDARD 1060-2000 FOR AIR-TO-AIR
ENERGY RECOVERY VENTILATION EQUIPMENT
The Air-Conditioning and Refrigeration Institute (ARI) issued
Standard 1060-2000 to certify air-to-air energy recovery ven-
tilators. This standard deals specifically with the ratings of the
Energy Recovery Wheel that is incorporated into the Energy
Recovery Ventilator (ERV). All of the York ERV's have an ARI
certified energy recovery wheel. The data shown in the spec-
ification charts is the ARI certified ratings for the wheel.
Actual performance in the ERV may vary.
Critical Terms for Standard 1060 are as follows:
1. Effectiveness. The measured energy recovery effec-
tiveness not adjusted to account for that portion of the
psychrometric change in the leaving supply air (Station
2) that is the result of leakage of entering exhaust air
(Station 3) rather than exchange of heat or moisture
between the air streams.
2. Net Effectiveness. The measured recovery effective-
ness adjusted to account for that portion of the psycho-
metric change in the leaving supply air (Station 2) that is
the result of leakage of the entering exhaust air (Station
3) rather than exchange of heat or moisture between the
air streams.
3. Exhaust Air Transfer Ratio (EATR). The tracer gas
concentration difference between the leaving supply air
(Station 2) and entering supply (outdoor) air stream (Sta-
tion 1) divided by the tracer gas concentration in the
entering exhaust (return) air (Station 3) at the 100%
rated air-flow, expressed as a percentage.
4. Outdoor Air Correction Factor (OACF). The entering
supply (outdoor) airflow (Station 1) divided by the mea-
sured (gross) leaving supply airflow (Station 2).
ENERGY RECOVERY WHEEL
The heart of the Energy Recovery Ventilator is the Energy
Recovery Wheel (defined by ARI as a rotary heat exchanger).
The wheel has a patented design of parallel layers of
wrapped polymeric material that is impregnated with a silica
gel (desiccant). This unique design makes it the only truly
cleanable wheel on the market today. The small wheels (30
inch diameter and smaller) are slide out cassettes, and the
larger wheels have pie segments that are removable for
cleaning.

CROSS LEAKAGE IN UERV’S (PURGE SECTORS)
The issue of cross leakage in rotary wheel based UERV's
used in space conditioning applications is often misunder-
stood. As a result, many systems are installed with purge
sectors and the additional fan capacity required to allow
these sectors to function when in fact they are unnecessary.
A better understanding of the rational for the purge sector,
and its history, allows us to dispense with the purge sector, its
added first cost and continuing cost of operation.
A purge sector minimizes the carry over cross leakage from
the exhaust into the supply (outside air) air stream by shunt-
ing a portion of the supply air back into the exhaust air stream
across the seal separating the exhaust and supply. This is
required in industrial applications where the exhaust carries
contaminants. This typically results in air volume being 15%
to 20% higher to get the desired air intake, and the cost asso-
ciated with it.
In space conditioning applications, where the ventilation is
operating to maintain acceptable indoor air quality, there are
no contaminants in concentrations large enough to cause
concern. Cross leakage in the UERV system results in a
small amount of the exhaust air, typically less than 5% in bal-
anced airflow, returning to the space. This is not contami-
nated air, as some would suggest. It is however air that
effectively never left the space. The operation cost of moving
this air is far less than that required for a purge sector. Do not
use the York UERV's in applications that have concentrations
of contaminants.

with the rooftop units. York provides a full line of roof curbs to
match the specified unit. See specification pages for required

HOW TO SELECT THE PROPER AIR
CONDITIONING UNIT AND UNITARY ENERGY
RECOVERY VENTILATOR
1. Determine the air conditioning load requirements with
the required amount of outside air without an UERV.
2. Select the proper UERV for the outside air CFM require-
ments and calculate the tonnage reduction through the
York UERV software program.
3. Select the air conditioning unit required by reducing the
load determined in step 1 by the reduction in step 2.
(Example: If the load in Step 1 was 10 tons, and the
reduction in Step 2 was 2.5 tons, select a 7.5 ton unit.)
4. Select the proper UERV based on the select unit. The
York part numbering scheme is as follows:

Note 1: Complete York ERV model number includes the electrical information. Example: DM180 needing 2800 CFM
outside of air at 230 volts/3 phase. Model would be a VR028A15H2AAA1.
Note 2: For VR074 and VR122 units used with an economizer must have the Start-Stop-Jog (SSJ) option.
TABLE 3: PERFORMANCE - 15 THROUGH 25 TON UNITS
Use this table to determine ventilation and size requirements. Table shows York packaged units and matching ERV model,
Air Flow Range, and ARI rated Net Effectiveness at 100% of rated CFM.
