EVI SCROLL AIR TO WATER HEAT PUMPS
This series air source heat pumps are specially designed for cold
climates and to work in outside air temperatures of -30°C. Its core
philosophy is to solve the user‘s home heating requirements during
winter and spring and provide cooling during a hot summer and
autumn. High temperature EVI Scroll compressors are equipped with a
vapour injection connection for Economizer Operation. Effective
enhancement is accomplished by utilising a sub cooling circuit, it
also increases heating capacity. The system is readily capable of
reaching an outlet water temperature of 65°C
The refrigerant from the condenser is undercooled and then
throttled, and then entered the evaporator to melt the frost layer
on the evaporator. Compared with the commonly used reverse cycle
defrosting, there are essential differences.
(1) Defrosting in the normal heating at the same time, does not
affect heating and indoor load.
(2)It can better adapt to the defrosting requirements of fin heat
exchanger in different environments and different parts, and do
point-to-point accurate defrosting.
(3) Defrosting does not require any other energy, continuous
constant heating efficiency.
(4) Set in the light frost, the frost will be removed, so that the
unit in the frost-free state of operation.
Automatic scale removal and unique nitrogen bead antifreeze
technology can effectively extend the high efficiency of heat
exchanger service time and heat transfer efficiency.
Single chip microcomputer is a single chip microcontroller, chip
integrated computer system, equivalent to a micro computer. Bo lang
single chip microcomputer control system logic control careful,
small volume, light weight, strong stability, can deal with various
operating conditions and protection measures.
Adopt EVI air injection technology, double stage compression,
improve heating efficiency, even under -25° C environment can be
efficient operation.
Adopts American gold aluminum fin evaporator technology, precious
metal nano double layer coating, defrosting more quickly.
Effectively improve the evaporation efficiency of air and rain
water, dust is not easy to accumulate, to ensure that -25℃ can also
have a strong heat transfer.
Triple sound insulation and heat insulation
· The machine adopts triple sound insulation cotton, together with
special shock absorbing pad, equipment foundation platform and
customized fan, which can reduce the noise caused by operation
vibration to below 55 dB.
· At the same time, it can effectively avoid the contact between
the host and the outside low-temperature air, and protect the
stable operation of the unit in the low-temperature environment.
