HRVCCSHA

The Heat Recovery Ventilation (HRV) system offered by Carrier

is the finest on the market today. The HRV 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 the Carrier HRV

the quietest on the market and ensures that comfort is felt, not

heard.

Unlatching two (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.

OneTouch Control:

Allows control of ventilator with the touch of a button. This

control will operate as a main wall control. The OneTouch will

operate the unit in Intermittent Mode (20 minutes per hour),

continuous low speed, continuous high speed, and off.

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.

Methods to Size HRVs

Method 1:

1. Calculate cubic feet of occupied space

2. Multiply by recommended air changes per hour (AC/h)

3. Divide by 60 minutes per hour to convert to CFM

Example: 2000 sq ft with 8 ft ceiling

0.35 air changes per hour (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 bathrooms times 20 CFM/each

3. Add25CFMforkitchen

Example: 2 people

2 bathrooms

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.

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

HRVCCLHA1250 is 8417 BTUh. This additional load should be

taken into consideration when sizing the heating equipment.

The cooling load chart shows the loads in BTUh also. 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 following psychrometric chart.) 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 HRVCCLHA1250

would have an additional cooling load of 6428 BTUh. This

additional load should be taken into account when sizing the air

cooling equipment.
