YORK UERV MODEL NOMENCLATURE

246681-YTG-B-0607

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 substantial 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 polymeric material that are impregnated with silica gel (desiccant). 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 acceptable. During economizer operation, the UERV exhaust blower continues to run, providing power exhaust for the system. 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 ventilators. 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 specification 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 effectiveness 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 effectiveness adjusted to account for that portion of the psychometric 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 (Station 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 measured (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 misunderstood. 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 shunting 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%

TABLE 1: UERV OUTSIDE AIR CFM SELECTION BY CFM

to 20% higher to get the desired air intake, and the cost associated 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 balanced airflow, returning to the space. This is not contaminated 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.

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 requirements 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:

SEQUENCE OF OPERATION:

Fixed Models - Normal Operation

1.

The space thermostat sends a signal to the RTU for cooling, heating or fan only operation.

2.

The ERV is activated simultaneously with the supply blower of the RTU. The intake blower, the exhaust blower, and the wheel rotation motor of the ERV are activated. These motors will remain energized as long as the supply blower on the RTU is energized. The RTU is in standard (non-economizer) mode.

3.

If the optional motorized fresh air damper in the outside air intake of the ERV is present, it opens and the ERV is energized.

4.

If the optional low ambient kit is present, and the temperature leaving the exhaust side of the wheel drops below the field adjusted set point on the temperature sensor of the low ambient kit, the optional motorized fresh air damper will close and the intake blower will de-energize.

The exhaust air blower and wheel rotation motor will continue to operate. When the temperature sensor has a sixteen-degree rise, the wheel is defrosted and the optional motorized damper will open and the fresh air blower will reactivate.

Pivoting Models - Normal Operation

1.

The space thermostat sends a signal to the RTU for cooling, heating or fan only operation.

2.

The ERV is activated with the supply blower of the RTU.

The intake blower, the exhaust blower, and the wheel rotation motor of the ERV are activated. These motors will remain energized as long as the supply blower on the RTU is energized and the RTU is in standard (noneconomizer) mode.

3.

If the optional motorized fresh air damper in the outside air intake of the ERV is present, it opens and the ERV is energized.

4.

If the optional low ambient kit is present, and the temperature leaving the exhaust side of the wheel drops below the field adjusted set point on the temperature sensor of the low ambient kit, the optional motorized fresh air damper will close and the intake blower will de-energize.

The exhaust air blower and wheel rotation motor will continue to operate. When the temperature sensor has a sixteen-degree rise, the wheel is defrosted and the optional motorized damper will open and the fresh air blower will reactivate.

Pivoting Models - Economizer Operation

1.

The space thermostat sends a signal to the RTU for cooling operation.

2.

The outdoor air sensor for the RTU senses the outdoor air and determines it is appropriate for economizer operation.

3.

As the economizer outside air dampers open, the ERV economizer end switch is activated sending a signal to the ERV that the system is in the economizer mode.

4.

The intake blower, the exhaust blower and the wheel rotation motor all deactivate for up to two minutes. The optional motorized fresh air damper (if present) also closes.

5.

The ERV enthalpy wheel pivots out of the air stream and the bypass dampers along each side of the intake blower open.

6.

After a time delay to allow the wheel to pivot out of the airstream and the bypass dampers to open, the optional motorized fresh air damper opens to allow for full economizer operation, and the exhaust blower is reactivated to provide power exhaust for the system.
