Electric convectors are used for rooms with a wet regime. Ventilation. The working project envisages the installation of a system of general exchange supply and exhaust ventilation with mechanical drive for the premises of the PRU - systems P1, B1, P2, B2 in the "clean ventilation" mode. Supply systems P1 and P2 are equipped with anti-dust filters (cassette filter G4 F315). Air intake and exhaust for ventilation systems is carried out from the outside, through separate ventilation shafts. In the cold period of the year, outdoor air heating is provided for P1, P2 systems. Plumbing. The connection of the B1 cold domestic drinking water supply system is made from the existing water pipe laid in the basement of the lyceum. The designed external water supply network is designed as an independent route with a length of 37.2 m in plan made of polyethylene pipe. It is planned to place an emergency supply of drinking water in a capacity of 1900 liters. Hot water supply is provided autonomously from electric storage water heaters. Sewerage. Drainage of the sewage system is provided through the release of K1 into the designed external sewage networks. Drainage of household sewerage from the building of the public utility company is carried out by two networks: the main and emergency K1 and K1.1. The main network is designed by gravity section K1n (length in plan 31.8 m) and gravity section K1 (length in plan 4 m) to projected well 1 (the point of insertion into the existing network of gravity sewage of the lyceum). The emergency network is carried out by gravity network K1.1 (length in plan 23 m) to the prefabricated designed well. Electrical solutions. The total existing power of the lyceum will not increase due to the existing reserve power and during the use of the storage, other electrical equipment of the building will not be operated. Electricity accounting - in the existing HRS. The project provides working and emergency lighting. Lamps with LEDs are designed in the premises. Emergency lighting and a wireless call button are provided in room 9 "Universal cabin (for MGN)". Evacuation lamps, "EXIT" light indicators, designed with built-in rechargeable batteries.
