Most Efficient Cold Climate Heat Pump
Air source heat pump:
Heat pumps are becoming more and more popular as an effective low-carbon
heating solution. These systems use electricity to harness the energy in the
surrounding air and deliver this energy to the room in the form of heat-much
like the reverse of air conditioning. These systems can achieve efficiencies
three to six times higher than traditional heating technologies.
Despite its obvious efficiency and carbon benefits, air source heat
pumps have historically been downgraded to a milder climate. So what should
we do in cold regions?
Cold climate heat pump:
Cold climate heat pumps are a revolution in heat pump technology and are
still unparalleled in terms of cost and performance. Our engineers designed
this heat pump with the mission of making it the most efficient cold climate
heat pump on the market, at only 1/2 the price of a traditional geothermal heat
pump. This is done without sacrificing quality. The design of the device uses
industry-leading components. This includes variable speed pumps, Panasonic EVI
DC inverter compressors, European Sanhua valves and Chico digital control
systems. All of these are directly used in the complete weatherproof enclosure.
Integrated heating solution
Unlike any other cold climate heat pump system on the market, our cold
climate heat pump can control the heating and cooling needs of your entire
home, including domestic hot water. The heat pump integrates multiple heat
sources, such as; radiant floor heating/cooling, forced ventilation center Air
handlers, split fan coils for heating individual rooms, low-temperature
radiators can also be integrated into any swimming pool or hot tub to provide
sufficient heat through our titanium heat exchangers. The outdoor installation
(ODR) contains everything you need in one box (whole). This results in no need
to hire refrigeration technicians. All you need is an electrical connection
with an outdoor rated disconnect device (weatherproof). This system requires a
240 VAC connection and dedicated circuit breakers for 20, 30, 40 Amp, depending
on the size of your heat pump.
Scalability
Our technology does not divide our products into 5 or 6 sizes, but
allows us to combine heat pumps to form larger heating systems as needed. With
our MX controller, you can add up to 10 heat pumps. Our design works in
parallel, so each unit has its own pump, but the controller will manage all
heat pumps as if they were a large heat pump.
User-friendly controller
Unlike other cold weather heat pumps that require direct communication
with each zone, our heat pumps use simple differential controller logic, which
includes a tank thermometer probe. Our storage tank has a special copper probe
port insert on the top and bottom, so we can accurately measure the storage
tank. The heat pump will be automatically optimized to reach the design
temperature set for the water tank. As the weather changes, the heat pump also
changes, using only what it needs to keep the buffer tank at the set temperature.
It can do this by changing the frequency of its DC inverter compressor to
increase or decrease power as needed.
So how does it work?
Our factory controller system can manage heating or cooling or both at
the same time.
1. Heating
2. Cool
3. Heating and cooling
4.+ Domestic hot water (with optional internal HX coil)
If we set up heating, the heat pump will turn on and start the
circulation pump and heat the buffer tank unit to the desired set point
temperature. The cooling method is the same, the only difference is that the
buffer tank is a special foam tank designed to not sweat and condense. When the
buffer tank reaches the set low temperature, the heat pump will shut down.
We can also set heating and cooling at the same time, for example, in summer
when you want to cool the house and heat domestic hot water. In this case, we
use the optional internal HX in the buffer tank. It is 160 feet of copper and
can achieve an efficiency of 94-97%. In this mode (heating and cooling), the
Air to Water heat pump will first heat the hot water buffer tank to ensure that
there is hot water, then activate the three-way valve and switch to the cooling
tank and reverse its function to cool. If the domestic hot water is not needed
in summer, it can be heated and cooled on a water tank.
What system is most suitable for air-to-water heat pumps?
As with most geothermal installations, we use R410a environmentally
friendly Freon, the characteristics of this refrigerating liquid produce a
maximum design temperature of 60C (140 F). However, we recommend that the
system design temperature be lower than 51C (125F) to maximize the performance
of the heat pump. Therefore, radiant floor heating is an important source of
heat for our ATW heat pumps. However, we also provide independent wall-mounted
fan coils for room partitioning. These special circulating fan coils are
designed around the 110-120 F water supply temperature range and can provide
heating and cooling. For central heating and cooling, our heat pumps can be
perfectly matched with air-to-water heat pumps because they have specially
designed 6-layer heat exchangers that are optimized to provide excellent
performance at temperatures of 120 F or lower.
Swimming pool or hot tub and heating/cooling
Swimming pool or hot tub and heating/cooling – By using an external heat
exchanger, we can also heat the swimming pool or hot tub. In this design, the
heat in the pool can be removed from the buffer tank or heat pump when it is
turned on. By adding a second loop and heat exchanger, any of our designs can
be used to realize this type of pool heating system. Or, if the swimming pool
is large, we recommend using our independent low-temperature pool heat pump,
which has an operating temperature of -10 C (14F). They have a built-in titanium
heat exchanger.
Final words
Buying cold climate heat pumps not only improves the quality of indoor
life, but they are also very efficient. In the long run, you can save a lot of
money.
However, you also need to be careful to purchase the right products. To
find the best heat pump for your cold climate, you need to consider several
things.
1. What size apartment or house do you have? This is a very important
piece of information, because it is the main factor in choosing a heat pump
that is powerful enough but not too powerful, because you will pay extra
without any benefit.
2. The house has good thermal insulation effect and good windows. These
are also important items that we must consider, and directly affect the amount
of power that the heat pump must be able to provide.
3. What kind of system do you want to connect the heat pump to? You have
a low-temperature floor heating or a high-temperature system with a radiator.
This will have a huge impact on your choice.
