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.
This system provides a comfortable indoor environmentconditions. In the summer, cold air is supplied to the room, and inthe winter, on the contrary, warm air.Depending on the design, switching mode "winter-summer" canbe a redirect air flow, and by reversing the flow in the system. Thecost of electricity for driving the compressor constitute 20-25% ofthe capacity of the system. On average, for living quarters, the airconditioner cooling capacity of 13 kW per 1 m2 of floor area or 77watts per 1 m2. At the same time the cost of electricity will be atleast 15 W per 1 m2 .. The room heating is required 1 kW to 10m2. Consequently, power consumption in the winter time toincrease to 20 W per 1 m2. This is a fairly high powerconsumption. So for example, for a flat area of only 50 m2 totalcosts per month amount to no less than 720 kWh of electricity.The main advantage of this system is very simple in low costequipment and ease of installation.The disadvantages of this system:
• Low energy efficiency and irrational large heat loss;• High operating costs.

The combined system providescomfortable conditions in the room andhot water.Main advantages:• In the summer, hot water does not
require additional costs.• Heating during the winter can be
carried using a water system withnatural circulation.
• External air intake fan runsoccasionally, when the water system isfully charged.
• In winter, the system can work only inthe daytime, when the outdoortemperature is higher than at night.
• The presence of the water circuit canreduce power installation, which inturn will reduce the cost of equipment.
• Thus, the system is more efficient interms of energy, and total costs arereduced by 1.5-2 times.
Of particular note is that the airconditioning cost is 3 times lower thanthe solar water heating system is apower. Using this system, you both getand 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 hotwater. Additional solar collector, which is included in themain loop operates as an additional compressor. As aresult, power consumption of the compressor decreasesin 2 - 3 times. Ideally, when a powerful solar radiationelectric compressor power consumption will tend to zero.At night, or when falling solar radiation intensity, the roleplayed by the additional compressor water heater isincluded in the reverse mode.This system has the same advantages as the previous one,except that, in the presence of the solar collector systemfurther 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 andbattery allows almost completely abandon the externalpower supply. Thus the cost of air conditioning, heatingand hot water are reduced to zero.

Нeat accumulator
Heat accumulator battery serves as heat andcold at different times of the day. The airintake for the supply to the evaporatorthrough the heat accumulator. Thus, such astructure allows the following:First, in the summer heat accumulator canaccumulate overnight and cool to use it atthe 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. Atnight you can use a cheaper night rate electricity.Third, in the winter the heat accumulator will accumulateheat until the temperature.
Ambient air is above zero, and thensupport it, when the ambienttemperature falls below zero.Fourth, the heat accumulator can serveas a heat recovery boiler wastewater,kitchen hoods, fire and so on. It is veryimportant.

Electricity from solar photovoltaic panels hasseveral disadvantages. Firstly, solar panelsoperate only when the solar energyavailable. Second, solar photovoltaic panelsare quite expensive and the payback periodis not less than 5 years. Third, the solarpanels produce direct current and additionalexpensive equipment is required to beconverted into alternating current withstandard parameters.Under these conditions, significantly moreefficient installation of the turbogenerator,that generates alternating current withstandard network parameters.
