Carrier 25VNA Operation manual

Product Data

25VNA

InfinityrVariable Speed Heat Pump

with GreenspeedtIntelligence

2to5NominalTons

Carrier’s 25VNA with GreenspeedtIntelligence is a breakthrough

product providing up to 13 HSPF heating efficiency and up to 20.5

SEER cooling efficiency. The variable speed capacity control

results in strong heating capacity as the outdoor temperature drops

resulting in less reliance on auxiliary heat. Lower speed operation,

when needed in cooling, for enhanced comfort and

dehumidification.

This product has been designed and manufactured to meet Energy

Starrcriteria for energy efficiency when matched with appropriate

coil components. Refer to the combination ratings in the Product

Data for system combinations that meet Energy Starrguidelines.

NOTE:Ratings contained in this document are subject to

change at any time. Always refer to the AHRI directory

(www.ahridirectory.org) for the most up--to--date ratings

This product has been designed and manufactured to

meet Energy Star®criteria for energy efficiency when

matched with appropriate coil components. However,

proper refrigerant charge and proper air flow are critical

to achieve rated capacity and efficiency. Installation of

this product should follow all manufacturing refrigerant

charging and air flow instructions. Failure to confirm

proper charge and air flow may reduce energy

efficiency and shorten equipment life.

LONG LINE APPLICATIONS

An application is considered Long Line when the refrigerant level in the system requires the use of accessories to maintain acceptable

refrigerant management for systems reliability. Defining a system as long line depends on the liquid line diameter, actual length of the tubing,

and vertical separation between the indoor and outdoor units.

For Heat Pump systems, the chart below shows when an application is considered Long Line. Beyond these lengths, long line accessories

are required:

* Make sure duct work is capable of delivering required airflow . Make sure combination rating exists for desired combination.

MIN/MAX AIRFLOW TABLES

The indoor airflow delivered by this system varies significantly

based on outdoor temperature, indoor unit combination, and

system demand. The airflows on these tables are for duct design

considerations. Duct systems capable of these ranges will ensure

the system will deliver full capacity at all outdoor temperatures.

Minimum and maximum airflows can be adjusted from these

numbers in the Infinity Control Heat Pump Setup screen.

* For tubing set lengths between 80 and 200 ft. (24.38 and 60.96 m) horizontal or 20 ft. (6.10 m) vertical differential (total equivalent length), refer to the Long

Line Guideline—Air Conditioners and Heat Pumps using Puron®Refrigerant.

{Required on all indoor units. Standard on all new Greenspeed™ compatible fan coils and furnace coils.

Accessory Description and Usage (Listed Alphabetically)

1. Compressor Start Assist

The inverter drive gently starts the variable speed compressor at all

times. No other start device is compatible with this unit.

2. Crankcase Heater

Compressor motor winding resistance heater which is internal to

compressor to keep the lubricant warm during off cycles. Improves

compressor lubrication on restart and minimizes the chance of

liquid slugging.

Usage:

Used in low ambient cooling applications.

Used in long line applications.

3. Liquid--Line Solenoid Valve (LLS)

An electrically operated shutoff valve which stops and starts

refrigerant liquid flow in response to compressor operation. It is to

be installed at the outdoor unit to control refrigerant off cycle

migration in the heating mode.

Usage Guideline:

An LLS is required in all long line heat pump

applications to control refrigerant off cycle migration in

the heating mode. See Long Line Guideline.

Suggested for all commercial applications.

4. Snow Stand

Coated wire rack which supports unit 18 in. (457.2 mm) above

mounting pad to allow for drainage from unit base.

Usage Guideline:

Suggested in the following applications:

Heat pump installations in heavy snowfall areas.

Heat pump installations in snow drift locations.

Heat pump installations in areas of prolonged

subfreezing temperatures.

All commercial installations.

5. Thermostatic Expansion Valve (TXV) Bi--Flow

A modulating flow--control valve which meters refrigerant liquid

flow rate into the evaporator in response to the superheat of the

refrigerant gas leaving the evaporator.

Usage Guideline:

Accessory required to meet AHRI rating and system

reliability, where indoor not equipped.

Required in all heat pump applications designed with

Puron refrigerant.

6. Electro--Magnetic Interference Kit

Usage Guideline:

May be required to address radio frequency interference

for equipment, such as HAM radios, operating between 6

and30mHz.
