Heat system
A Heat system includes a set of solar collectors and a heat accumulator. Antifreeze, heated in a solar collector, transfers heat to water in the accumulator through a heat exchanger. Energy is being stored in the summer and is taken in the cold season. The "warm floors" are used as heating devices in this system, which, unlike traditional radiators, work effectively even at low heat accumulator temperatures.
The heating system includes a heat accumulator, an expansion tank, a circulation pump, a heat exchanger, a three-way controlled valve and heaters. The heat exchanger is used to heat the coolant in cooperation with a heat pump before it is delivered to the "warm floors".
The most important element in this system is the heat pump, which provides the hot water supply, the utilization of the heat of sewage and after heating the coolant of the main heating system. Under certain conditions can serve as the main heat generator.
The main advantage of this system is a full autonomy and almost threefold reliability, i.e. even if any of the components brokes down, the system compensates the losses due to the redistribution of loads in other nodes. The cowork of the main nodes makes it possible to utilize the capabilities of each of them and almost completely eliminate the influence of adverse weather conditions and peak modes (day to night, etc.).
The absence of traditional fuel and problems with its delivery and storage, an intelligent control system ensure the safety and comfort of operation of this system.

Heating system
The main elements of the heating system include:
Heat Pump
Heat Accumulator
Heating devices ("warm floors")
Three-way controlled valve
Heat exchanger
Circulation pump
Waste water heat recovery
Coolant temperature sensor
Summer period (heating off)
In this mode of operation, heating devices are turned off ("warm floors") and the system enters the mode of accumulation of thermal energy, which is determined by a number of additional parameters. In the daytime, the solar collector serves as the main source of energy for heating the heat accumulator, and when the wind generator is running, the heat pump becomes an additional source. If the temperature in the battery is below 60 ° C, the pump turns on, which circulates the battery coolant through a heat exchanger in which part of the heat pump condenser is located, which provides heating. In the absence of the sun or at night, this mode becomes the main one. All processes in the heating system are regulated by an automatic control system.
Heating season
The transition of the heating system to the main mode consists in connecting the heaters and circulating the coolant between the battery and the heaters. The temperature at the input of the heaters is set to a certain extent depending on the outdoor temperature and is monitored by a temperature sensor. Adjusting and maintaining the required temperature provides a three-way control valve, controlled by ACS, by mixing the coolant from the return collector to the system input. When the heat pump is running, the flow of coolant from the battery is completely stopped, which saves a significant amount of energy stored in the battery.
Heat pump system
The heat pump is the main component of autonomous power supply system and involved in almost all modes. Its high efficiency allows the most rational use of the excess energy produced by the wind generator and, in combination with cheap solar energy, ensures complete autonomy of the building's energy supply.
Hot water supply
One of the main modes of operation of the heat pump is the preparation of hot water. During the day, when it is turned on, the solar collector becomes the heat source, which significantly increases the efficiency of the hot water preparation process.
Wastewater heat recovery
Since the main consumption of hot water is associated with bathing or showering, the system provides a heat exchanger for wastewater from the bathroom, which is another source of heat for producing hot water. Before discharge into the sewage system, wastewater enters the utilizer, where heat is removed and recovered, which significantly reduces the cost of preparing hot water. A forced ventilation system with heat recovery is also provided.
Heating
When the wind generator is running, the main load of the heat pump is the heating system: in the summer, the heat accumulator is heated under the condition that the coolant temperature in it is below 60˚С, during the heating period the heat pump works directly on the heating devices, which significantly saves battery heat reserves.
Solar collector system - heat accumulator
The heliosystem is a closed loop, which in addition to the solar collector includes a heat exchanger placed in a heat accumulator, a circulation pump and an expansion tank.
Modes of operation of the solar collector are determined by the operation time of a day and the time of year. The main mode of operation is "day - summer", i.e. at the maximum level of solar radiation, when the temperature of the coolant in the collector can reach 100 ˚С. A circulation pump pumps the medium heated coolant in the collector through a heat exchanger where heat is collected by the battery water.

Automatic control system
The main source of electricity is a wind generator, connected to a network regulator, which provides the entire system with the necessary energy and constantly monitors the status of batteries. The regulator controls the degree of discharge of batteries and, if necessary, sends part of the energy to recharge the battery. In the case when the generated energy is not enough (for example, insufficient wind power), the regulator sends the missing energy from the battery through the inverter to the system, which converts the constant voltage of the battery into alternating power with an industrial frequency and ensures the constancy of power consumption.
The management of the energy system is fully automated. The automatic control system is based on a computer with the appropriate interfaces and software. It is powered by a separate rechargeable battery, which significantly increases its reliability. The input of the ACS receives signals from all sensors of the system in real time. The obtained information is processed by special software, which determines the further behaviour of all elements of the system.
