24VNA9 Infinityr19VS Variable Speed Air Conditioner
with Puronr Refrigerant
The Infinity 19VS variable speed air conditioner provides a flexible alternative to high‐priced
variable speed systems on the market today, as well as 2‐stage products currently being
offered. Its highly efficient, smaller and lighter design offers many benefits to dealers and
homeowners alike. This document outlines the recommended application parameters and
differences from other products.
Overview
The Infinity 19VS is an inverter‐driven variable speed air conditioner designed for the
ducted residential market. Its size and weight advantage makes it easier for dealers to
handle and stock, and allows for high-efficiency installations in tighter spaces than previously
possible. It is designed to complement the dealer's product offering by adding a new, unique
variable speed air conditioner to compete in this expanding market.
Benefits of Variable Speed
Variable speed systems provide several benefits to the homeowner. The capacity range of
the system allows it to more closely match the home's needs as conditions change. This
increases indoor comfort by running longer comfort cycles at lower speeds thus eliminating
up and down temperature swings. Longer cycles at lower speeds also translate into higher
efficiency, and lower overall sound levels both indoors and outside. The wide capacity range
also improves zoning and dehumidification capability compared to 2‐stage and 1-stage
systems.
