CO2 heat pump temperature range domestic and commercial heat pump 8
to 200kw
Description of CO2 heat pump temperature range domestic and
commercial heat pump 8 to 200kw
The upper limit of water temperature reaches 100℃;
Working limit -43°C water 100°C;
Natural refrigerant, high energy efficiency ratio (COP);
At the same time, the production of cold and hot water multi-tank
heat storage and high stratification work, based on high
temperature storage, the water tank capacity can be reduced, and a
large amount of water can be met.
Multi-module (eight at the same time);
Safety (with 6 high-voltage safety protection, water and
electricity separation);
The core control components of the unit adopt Italian Carle PLC and
CPP;
The units are equipped with Italian Duling dedicated CO2 piston or
Panasonic dual-rotor compressor;
The unit uses electronic expansion to achieve continuous control
and expansion of refrigerant flow;
The unit has a built-in Wilo water pump and is controlled by
frequency conversion to obtain high-precision outlet water
temperature;
The casing of the unit is made of galvanized sheet and sprayed, the
water receiving tray and the water inlet and outlet of the unit are
made of 304 stainless steel, and the added aluminum filter screen
effectively protects the heat exchange efficiency of the
evaporator.
application range /
CO2 heat pumps are the ideal solution for installations with high
temperature hot water needs
Ideal place to use:
Hotels / Restaurants / Factory and School Canteens / Residential
and Tourist Buildings / Sports Centers
Hospitals / Industrial Food Sterilization / Dry Cleaners and
Textile Manufacturing / Cement Manufacturing / Wherever hot water
is needed
The frequency can be automatically changed in real time to achieve
the most efficient operation (the most efficient production of hot
water)
The unit operates independently in summer (to meet the efficient
operation of the heat exchanger)
In heating conditions, it can be controlled by itself according to
the heat load (to achieve efficient heating at -30 degrees)
When the unit has high temperature and high pressure, the unit is
self-variable (safer)
In summer, the fan reduces energy consumption by itself (the fan
can save energy by 50%)
Reduced grid impact through variable frequency drive, extended
compressor life (durable)
Dedicated algorithm for maximum COP
With the COP automatic tracking system, the alternatives on the
market are unmatched.
The parameters can be automatically changed in real time to achieve
the most efficient operation.
When the working conditions are changed, the variable flow through
the electronic expansion valve.
Management control, which effectively ensures the maximization of
cop.
【safe and stable】
The core control components are original from Italy, Japan and
Germany
Human interface, intelligent cloud service, remote management
The unit operating parameters and fault information are uploaded to
the client or intelligent cloud service system in real time;
Separation of water and electricity, constant water temperature,
non-toxic and non-flammable working fluid;
The refrigeration system is designed with 6 high-voltage protection
devices;
Compressor and water pump are controlled by frequency conversion.
【Low temperature operation】
Intelligent frost and antifreeze to break the low temperature limit
Work safely and stably in the environment of -30°C-43°C, and
continuously provide 90°C hot water to break the "boundary" of use
Intelligent detection of defrosting requirements, frequency
conversion control can save 50% energy than traditional or other
similar products;
Professional frequency conversion incremental control to meet the
requirements of different water consumption in different
environments
【Energy saving and environmental protection】
Real-time automatic parameter conversion (frequency conversion), to
achieve the most efficient operation (COP=4.8), natural products
Non-flammable, non-flammable, natural product, good compatibility,
low cost; no need to re-acquire;
ODP = 0 (Ozone Threat Potential 0) GWP = 1 (Greenhouse Potential
1);
not be bound by any country's tax and regulatory regulations;
With COP automatic tracking system, it can automatically change
parameters in real time to achieve the most efficient operation;
The intelligent variable frequency control of the compressor pump
and the variable flow management control of the electronic
expansion valve effectively ensure the maximization of COP.
Hot water]
Maximum water temperature up to 98°C Ideal for industrial
applications
The water temperature is as high as 98°C, and the water temperature
is much higher in efficiency and temperature than traditional HFC
refrigerants for heat pumps;
The high-temperature hot water at 95°C can be produced, and the
thermal efficiency is 2.5 times higher than that of traditional
electric heating;
Such high temperature water effectively prevents the formation of
Roman legions.
Installation Notes:
1. The spacing around the installation must not be less than Im;
2. The pipelines other than the heat pump should be protected from
frost and heating elements can be installed;
3. Heat insulation and protection measures should be taken for the
pipelines for hot water circulation to prevent heat loss.
