Introduction

The course design was developed on the basis of the requirements of SNiP 41012003 "Heating, ventilation and air conditioning," SNiP 2.04.0185 "Internal water supply and sewerage of buildings," SNII379 * "Builder-naya heat engineering," SNiP 230199 * "Construction climatology" and SNiP buildings protection. "Thermal 23022003"

The cottage construction area is the city of Vladivostok. Vladivostok was stretched by an amphitheater on the southernmost tip of the peninsula of MuravevaAmurskiy. The entire peninsula, along with a chain of islands stretching south of it, enters the city limits. The peninsula of MuravevaAmurskogo is extended from the northeast on the southwest and width of its 12 km presses in the sea approximately on 37 km. The peninsula is washed from the west by the waters of the Gulf of Amur, from the south by the waters of the Golden Horn, Diomides, Bolshoi Ulysses, Patroclus and the Strait of Bos Fora Vostochny, from the east by the waters of the Ussuri Bay.

The rugged coastline gives Vladivostok and its environs a special charm. And if you look at the city from one of the hills, then a wonderful view will open to the entire southern part of the peninsula, to its nearest islands, Amur and, partially, Ussuri bays. The relief of the peninsula is mountainous. Hills are located from northeast to southwest and are largely dissected by decays and valleys of small rivers.

The rivers of the city have a sharp transition from large slopes to almost zero. During showers, such a sharp slope difference creates conditions for flooding of the floodplain of the middle and lower parts of the rivers.

The beginning or end of those months in which the average daily tempera-tour passes through the corresponding limits was taken abroad from climatic seasons. For winter, such a limit is the steady autumn and spring transition of average daily temperatures through 0 ° C. Spring and autumn are limited by the transition of average daily air temperatures through 0 and 10 ° C (downward and upward). For summer, the limit is a steady transition through 10 ° C.

In winter, the city is dominated by dry and cold continental air, causing clear frosty weather. January is the coldest month of the year: the average monthly temperature is 13.5 ° C. Name-no this month recorded an absolute minimum air temperature of 30.3 ° C (January 10, 1931).

Thaws in Vladivostok are in any month of winter. Their longest duration is 1-2 days. During the winter, the city has up to 18 cloudy days and about 27 days with precipitation. Precipitation falls in the form of snow. But in some years, mixed precipitation and even rain are possible. Snowstorms in the city are 8-9 days. It is not uncommon when the wind speed with blizzards increases to 15-20 m/s, and then snow drifts are noted, leading to the cessation of transport and the cessation of work. In winter, perhaps all atmospheric phenomena are found in the city, except for hail.

Summer occurs when the average daily air temperature passes through 10 ° C. The average summer duration in Vladivostok is 142 days. The longest summer was noted in 1967 (174 days), the shortest - in 1969 (116 days).

A distinctive feature of the summer period is the instability of the weather. Significant clouds and fogs observed in the first half of summer reduce the flow of direct solar radiation and reduce the duration of hours of sunshine. The highest temperature (21 ° C) occurs in August, which is the warmest month of the year. The value of the absolute maximum is + 34.1 ° C (registered on August 21, 1921 and in July 1939). The summer months account for the greatest recurrence of heavy rains, which are brought to the city by typhoons, cyclones and frontal divisions. A record maximum of precipitation per day of 244 mm was noted on July 13, 1990 - Typhoon Robin brought down this avalanche of rain on the city.

In this work, communication systems are designed, such as a system of heating, ventilation, hot water supply, gas supply, cold water supply, sewerage. The task of this work is to provide comfortable conditions for living in an individual autonomous house, using autonomous heating, heat supply, and hot water treatment systems to solve this problem.

Also in this work, heat engineering calculation of enclosing structures was carried out, in accordance with modern requirements for energy saving.

A vertical double-tube heating system with a lower discharge line is adopted. Main heat lines are laid in the basement. As heating devices, the Global aluminum radiators of the VOX 500 model are adopted.

Heat carrier parameters in internal thermal network of 9570 wasps.

Heating system pipes are accepted as steel water and gas pipes. Thermal control valves are installed on the supply to the heating devices. Air from the heating system is removed through the Mayevsky air valve, which is installed on the upper heating device.

Mechanical plenum ventilation is accepted for the living room. In the ventilation system, RP1 grids are adopted as air distributors. The exhaust is natural.

Mechanical exhaust ventilation is accepted for kitchen, s/node on the first floor and for bathroom on the second through grilles type RV.

Hot water is heated in a gas boiler operating independently from the heating system.

Sewerage

The internal sewer network is designed from plastic pipes (GOST 22689.0... 22689.20 - 89). They have a small mass, high corrosion resistance, a smooth surface, providing non-burnability and low hydraulic resistance. Pipes are connected by bell joint with rubber ring.

Taps (GOST 22689.9.77), elbows (GOST 22689.977), straight and oblique crosses at an angle of 450 (GOST 22689.977), straight and oblique tees (GOST 22689.977), indents are used as plastic shaped parts.

Cleaning is arranged in places where cleaning of pipes is required only in one direction.

The bath bowl has a rectangular shape with overall dimensions of 1770x750 mm, The depth of the bowl is 460 mm. Baths are made of enameled cast iron. Bath reinforcement (filling and drain) is installed on the side of bathing legs. Drain valves include outlet closed by plug, overflow pipe, overflow cover. The outlet and overflow pipe are connected under the bath bottom by a tee, to which the hydraulic lock is connected - a floor siphon for the bath. The mixer is installed at a height of 1 m from the floor. Washbasins measuring 650x600 mm. equipped with mixers, the outflow of which is at a height of 200 mm from the side of the bowl. Washes are installed at a height of 800 mm from the floor. Toilets consist of a bowl, which smoothly passes into a hydraulic lock and base. The size of the toilet is 380x675 mm. The outlet at the bottom of the toilet ensures that it is connected to the sewer network.

Conclusion

In the course project, autonomous systems for a private residential building were designed and calculated. The construction area is the city of Vladivostok.

Heating system - vertical double-tube with lower wiring. Steel electric welded straight-joint pipelines. Heating devices - aluminum radiators of the Italian company "Global" model VOX 500 with a heat output of one section of 193 W.

Ventilation - plenum mechanical, exhaust - natural. C-system of hot water supply is designed with lower wiring. Hot water is prepared directly in the building, for which the OKCV 125 NTR boiler is used.

Gas supply - from the low-pressure main gas pipeline.

The boiler house for heating the country house consists of the following equipment: for the heating and ventilation system - a boiler with an atmospheric burner Buderus Logano G234 WS38, for the hot water supply system and "warm floor" - Ferroli Rendimax N 16 EL, boiler OKCV 125 NTR, pumps Grundfos, Copper Fittings, Expansion Tubing and Aning Aning

The boiler room is designed for heating a country house. In this country house there are the following heat consumers:

Radiator heating at home

Water "warm floors"

Capacitive water heater-system GVA

Heating system calorifer

In this boiler room, the circuit with a three-way mixer Danfoss VF3 with an electric drive is used for heat supply of radiator heating and heating of the ventilation system of the country house.

All boiler equipment piping is made of unburned KME honey pipe with Sanha copper fittings.

As shutoff valves in the boiler room of the country house, Bugatti ball cranes were used.

Coolant circulation is carried out by pumps manufactured by Grundfos.

Reflex 600 N membrane expansion tank is used to compensate for thermal expansions in the heating circuit, water warm floors and boilers.

In the GVA circuit for boiler protection, the Reflex N 100 membrane expansion tank is also used.

In the country house, a capacitive water heater (boiler) OKCV 125 NTR with a capacity of 125 liters with an active anode for corrosion protection is installed to heat hot water.

To control the temperature in the heating and ventilation system of the country house, a 3-way valve with an electric drive Danfoss VF3 is used.

The control unit monitors the outside temperature by the outdoor air sensor and, depending on it, controls the drive of the three-way mixer, sets the current value of the coolant temperature in the supply pipeline of the heating circuit of the country house.

To operate the warm water floor, it is necessary to maintain a relatively low coolant temperature in the supply line at 3055 ° C. Since the temperature in the boiler does not generally fall below 60 ° C, and the heating circuit of the house can reach 90 ° C, a three-way distribution valve Danfoss VRB 3 with a thermostat with a remote capillary temperature sensor is used to reduce the supply temperature in the water warm floor circuit.

As noted above, hot water is heated in the vertical storage boiler OKCV 125 NTR. It always has a hot water pass, the temperature of which is maintained at 60 ° C.

The Grundfos UPA120 pump with stainless steel housing is used to create comfortable use of hot water and provide sanitary requirements in the WAN circuit for circulation.

Combustion products are removed from the boilers of the country house through a chimney made of insulated polished stainless pipes of the type "sandwich" manufactured by F.F. Bofill.

To separate the primary (boiler) circuit from the secondary (heating) circuit, select the separator Magra 600.060.340.3F. When using a hydraulic separator, the pressure ΔP between the supply and return manifolds is close to zero.

The use of a hydraulic separator in the installation and installation of modern boiler equipment guarantees a long life of boilers, as well as their maximum safety. The use of the hydraulic arrow in the piping of domestic boiler houses greatly simplifies the design, installation and service work for their maintenance.
