Thermal testing of heating systems should be carried out within 7 hours, while checking the uniformity of heating of the heating devices (to the touch).
7. Starting heating systems
7.1. Acceptance into operation of heating systems, hot and cold water supply must be carried out in compliance with SNiP 3.01.04-87.
Before commissioning and handing over heating, hot and cold water supply systems to the operating organization, the work performer must check:
The state of insulation of heated buildings (sealing leaks in window and doorways, places where communications pass through the walls of the building, insulation stairwells and so on.);
Serviceability of thermal insulation of the heating unit, pipelines, fittings and equipment;
Availability and compliance with the calculation of restrictive diaphragms and balancing valves;
Availability and serviceability of instrumentation, control and safety devices;
The absence of jumpers between the supply and return pipelines of the heating unit and in the heating system or their reliable shutoff;
Compliance with the working documentation for connections of equipment of thermal units with water supply and sewerage.
7.2. Starting up a water heating system (and/or heat supply system, ventilation and air conditioning system, air-heat curtains) includes:
Emptying from tap water all systems filled during flushing or pressure testing;
Filling all systems with network water or filling previously unfilled systems with water from the heating network;
Creating circulation in the system using a pump;
Adjusting the start of the water system.
7.3. Before filling the heating system, all shut-off and control valves (with the exception of the first valves of the heating unit on the network side) and air valves in high points systems must be open, the first valves and drains must be closed.
7.4. Filling the heating system should be done by smoothly opening the first valve on the network side on the return pipeline of the heating unit. The water supply, controlled by the degree of opening of the valve, must ensure complete removal of air from the system. In this case, the pressure in the return pipeline of the heating unit from the network side should not decrease by more than a pressure of 0.03 to 0.05 MPa (0.3 to 0.5 kgf/cm2).
7.5. During filling of the heating system, continuous monitoring of the air valves is necessary. The air valves should close as air stops escaping and water appears.
7.6. After filling the heating system and closing the last air valve, you should smoothly open the valve on the supply pipe of the heating unit, which creates water circulation in the system.
7.7. If there are water flow metering devices (water meters) on the return pipelines, filling should be done through bypass lines; if there are no metering devices, filling should be done through an insert installed in their place. It is prohibited to fill the system through a water meter.
7.8. If the pressure in the return pipe of the heating unit is lower than the static pressure in the system, filling the heating system should begin through the return pipe. If there is no pressure (pressure) regulator on the return line of the heating unit, before starting to fill the heating system, install a throttle diaphragm taking into account SP 41-101-95, which will provide the necessary pressure at the calculated water flow in the system.
If there is a pressure regulator, the pipeline is closed manually.
When the first valve on the network side on the return pipeline of the heating unit is smoothly opened, the system is filled to the possible value determined by the pressure in the return pipeline. Further filling is carried out by smoothly opening the valve on the supply pipeline. Before performing this operation, in the absence of a pressure regulator, the valve on the return pipeline must be closed (not completely).
The valve on the supply pipe should be smoothly opened until the pressure in the heating system reaches the static pressure and water appears from the highest air valve.
The readings of pressure gauges and air valves must be monitored.
Before closing the last air valve, close the valve on the supply line and establish static pressure in the return line using the valve or by adjusting the pressure regulator spring. When closing the last air valve, you must carefully ensure that at the moment of closing the pressure in the return pipeline does not exceed the static pressure by more than 0.05 MPa (0.5 kgf/cm2).
7.9. After closing the air valve, the valve on the supply and return pipelines alternately open completely, and the pressure in the return pipeline must be maintained at a level exceeding the static one by 0.05 MPa (0.5 kgf/cm2), using a regulator or throttle diaphragm, taking into account SP 41-101-95. In this case, the pressure should not exceed that permissible for a given heat consumption system.
Note- When using a throttle diaphragm, it must be taken into account that it ensures the specified pressure in the system only when constant flow water for which the throttle diaphragm is designed.
7.10. After circulation is created, air is released from the air collectors at intervals of 2 to 3 hours until it is completely removed.
7.11. After turning on the heating system for full circulation, the pressure (pressure difference on the supply and return pipelines) and water flow at the heating unit must be equal to the calculated values.
If a deviation of the design pressure indicator by ±20% or more and water consumption by ±10% or more is detected, the causes of these deviations must be identified and eliminated.
7.12. Commissioning of heating, cold and hot water supply systems is documented in the acts given in Appendices D and E.
