Wheel Heat Recovery Type Rooftop Package Unit
Description:
1. Rooftop air conditioner generally have many functions such as
refrigeration,heating,air supply,easy to use,low cost installation,
low maintenance cost, widely used in air conditioning engineering
project.
2. Rooftop air conditioner,saving the cooling tower and cooling
water pump cost for customers, is particularly suitable for water
shortage area.It does not need special room for installation, and
can be installed on the roof or building ground outside
3. package unit heat pump is widely used in large space of
centralized air treatment, such as convention and exhibition
center,stadiums, theatres, shopping malls, supermarkets, waiting
room, conference room, production workshop, library,etc.
4. It is equipped with high performance compressor,low noise axial
flow fan, high precision grades of electronic expansion valve,and
advanced control system.
