2. Heat pumps are widely used for air conditioning, heating
and hot water supply of residential houses. On the one
hand, heat pumps are the most used energy of the
environment, and on the other hand, are the most
environmentally friendly. The heat pump can use the
heat of the ambient air, ground water, nearby bodies of
water, and so forth. However, the heat pump has a
number of disadvantages in its pure form. First, the heat
pump requires a heat source at a temperature not lower
than -15 ° C (the latest models can work to -25 ° C).
Second, the heat pump consumes a lot of electricity. The
conversion factor of 4 - 5 (the ratio of heat output to the
electric power consumption). Thus, with decreasing
temperature of the heat source, energy conversion rate is
reduced to 3.
We offer you combined systems that are devoid of
these shortcomings, and much more effective.
3. This system provides a comfortable indoor environment
conditions. In the summer, cold air is supplied to the room, and in
the winter, on the contrary, warm air.
Depending on the design, switching mode "winter-summer" can
be a redirect air flow, and by reversing the flow in the system. The
cost of electricity for driving the compressor constitute 20-25% of
the capacity of the system. On average, for living quarters, the air
conditioner cooling capacity of 13 kW per 1 m2 of floor area or 77
watts per 1 m2. At the same time the cost of electricity will be at
least 15 W per 1 m2 .. The room heating is required 1 kW to 10
m2. Consequently, power consumption in the winter time to
increase to 20 W per 1 m2. This is a fairly high power
consumption. So for example, for a flat area of only 50 m2 total
costs per month amount to no less than 720 kWh of electricity.
The main advantage of this system is very simple in low cost
equipment and ease of installation.
The disadvantages of this system:
• Low energy efficiency and irrational large heat loss;
• High operating costs.

The combined system provides
comfortable conditions in the room and
hot water.
Main advantages:
• In the summer, hot water does not
require additional costs.
• Heating during the winter can be
carried using a water system with
natural circulation.
• External air intake fan runs
occasionally, when the water system is
fully charged.
• In winter, the system can work only in
the daytime, when the outdoor
temperature is higher than at night.
• The presence of the water circuit can
reduce power installation, which in
turn will reduce the cost of equipment.
• Thus, the system is more efficient in
terms of energy, and total costs are
reduced by 1.5-2 times.
Of particular note is that the air
conditioning cost is 3 times lower than
the solar water heating system is a
power. Using this system, you both get
and cool air in the room and hot water.

The combined system, as well as the previous one,
provides a comfortable environment in the room and hot
water. Additional solar collector, which is included in the
main loop operates as an additional compressor. As a
result, power consumption of the compressor decreases
in 2 - 3 times. Ideally, when a powerful solar radiation
electric compressor power consumption will tend to zero.
At night, or when falling solar radiation intensity, the role
played by the additional compressor water heater is
included in the reverse mode.
This system has the same advantages as the previous one,
except that, in the presence of the solar collector system
further allows:
• Significantly reduce power consumption and improve
the efficiency under favorable weather conditions.
• The electricity consumption of the compressor drive is
reduced to 3 times.

The presence of additional solar photovoltaic panel and

power supply. Thus the cost of air conditioning, heating
and hot water are reduced to zero.

Нeat accumulator
Heat accumulator battery serves as heat and
cold at different times of the day. The air
intake for the supply to the evaporator
through the heat accumulator. Thus, such a
structure allows the following:
First, in the summer heat accumulator can
accumulate overnight and cool to use it at
the beginning of the day.
Second, if at night, produce reversing the evaporator fan,
the battery can store the cold and use it later in the day. At
night you can use a cheaper night rate electricity.
Third, in the winter the heat accumulator will accumulate
heat until the temperature.
Ambient air is above zero, and then
support it, when the ambient
temperature falls below zero.
Fourth, the heat accumulator can serve
as a heat recovery boiler wastewater,
kitchen hoods, fire and so on. It is very
important.

Electricity from solar photovoltaic panels has
several disadvantages. Firstly, solar panels
operate only when the solar energy
available. Second, solar photovoltaic panels
are quite expensive and the payback period
is not less than 5 years. Third, the solar
panels produce direct current and additional
expensive equipment is required to be
converted into alternating current with
standard parameters.
Under these conditions, significantly more
efficient installation of the turbogenerator,
that generates alternating current with
standard network parameters.
