Heat Recovery Ventilators
Copyright 2005 Carrier Corporation Form HRV-2PD
The Heat Recovery Ventilation
(HRV) system offered by Carrier is
the finest unit on the market today.
The HRVC provides efficient and cost-
effective heat recovery during the
heating season when needed most.
As temperatures drop below 23°F
(–5°C), indoor air is recirculated
periodically through the heat
exchanger core to prevent frost from
forming. Competitors’ methods of
supplementary electric defrost waste
energy. Unlike rotary wheel heat
exchangers which mix air streams,
these cross flow or counterflow heat
exchangers ensure that there is no
mixing of the stale air stream with
the fresh outdoor air stream.
A filter installed on the incoming
outdoor air stream removes large
airborne particles from the intake air
stream before they enter the heat
exchanger and reduces the
maintenance required.
The units’ acoustically engineered
design makes them the quietest on
the market and ensures that comfort
is felt, not heard.
Unlatching 2 suitcase style latches
allows easy removal of the filters and
core for cleaning.
Note: The HRV should not be
installed in an attic or unconditioned
space unless provisions are made for
drainline freezing and condensation.

Control features
Basic Control: Allows the user to manually set fan speed to low or high as required to maximize comfort.
Standard Control: Offers automatic dehumidistat control and the option to select continuous or intermittent fan operation.
Setting the wall control to low will activate the continuous mode.
Automatic Control: In addition to the features found with standard control, this package offers a recirculation mode. These
controls may only be used to operate stand-alone units with the defrost option which enables the recirculation feature.
* Air exchange with outside.
† No air exchange with outside.
‡ Use only on units with defrost.
Control description and usage
Fan Speed Control — Enables user to modulate fan speed from low to high air exchange with outside.
Dehumidistat Control — Allows the user to select the relative humidity level at which the unit would change fan speed for
dehumidification in the winter months.
Continuous Mode — If the relative humidity inside the building is lower than selected, air exchange occurs with the outside
at low speed. If the relative humidity inside the house is higher than selected, air exchange occurs with the outside at high
speed. Ensures continuous air exchange for constant air quality.
Intermittent Mode — If the relative humidity inside the building is lower than selected, no air exchange occurs and the
system turns off. If the relative humidity inside the house is higher than selected, air exchange occurs with the outside at high
speed. Ensures minimum air exchange level when the building is unoccupied to minimize operating costs.
Circulation Mode — If the relative humidity inside the building is lower than selected, the ambient air would be circulated
and filtered at high speed. If the relative humidity inside the house is higher than selected, air exchange would occur with the
outside at high speed. Ensures continuous movement and filtration of air for maximum comfort. Available with automatic
control only.
Automatic defrost cycle features
All models offer a non-electric defrost cycle feature which prevents frost and ice buildup within the heat recovery core. When
the outside air temperature falls below 23°F (–5°C) it is electronically sensed and the dampers close the outside air ports. This
allows warm indoor air to recirculate within the heat recovery core. The frequency of this cycle increases as the outside air
temperature decreases.
* All defrost times are in the standard mode (as shipped)
† Time between defrost when within specified temperature range

Methods to size HRV’s
METHOD 1
1. Calculate cu ft of occupied space.
2. Multiply by recommended air changes per hr (AC/h).
3. Divide by 60 minutes per hr to convert to CFM.
EXAMPLE: 2000 sq ft with 8 ft ceiling
0.35 air changes per hr (AC/h)
(2000 sq ft x 8 ft ceiling x 0.35 AC/h) / 60 min/h = 93.3 CFM
METHOD 2
1. Multiply number of people times 15 CFM/person.
2. Multiply number of bath rooms 20 CFM/each.
3. Add 25 CFM for kitchen.
EXAMPLE: 2 people
2 baths
1 kitchen
(2 x 15) + (2 x 20) + 25 = 95 CFM
Additional heating and cooling load charts
Although the ventilators process the outside air before it enters the home, additional heating and cooling loads need to be
considered.
Heating load BTU
The heating load chart shows the heating loads in Btuh for a range of winter design temperatures for each model of ventilator.
EXAMPLE: The heating design temperature for Milwaukee, WI is –4°F. At –5°F, the additional heating load of the
HRVCCLHU1250 is 8417 Btuh. This additional load should be taken into consideration when sizing the
heating equipment.

Cooling load BTU
The cooling load chart shows loads in Btuh as well. To use the cooling load chart, first find the design enthalpy from a
psychrometric chart using the design dry bulb and wet bulb temperatures. (See psychrometric chart on p. 11.) The cooling
load can then be found for a range of enthalpies for each ventilator.
EXAMPLE: The cooling design dry bulb temperature for Milwaukee, WI is 87°F and the average wet bulb at that
temperature is 73°F. On the psychrometric chart the enthalpy is about 37.7 Btu/lb of dry air which will round
up to 38 Btu/lb of dry air. In the left column, at 38 Btu/lb the HRVCCLHU1250 would have an additional
cooling load of 6428 Btuh. This additional load should be taken into account when sizing the air cooling
equipment.
