Introduction

The working design of the heat energy and coolant metering unit was developed on the basis of the following documents:

Specification No. 04257 issued by TSiS Enterprise No. 1 of State Unitary Enterprise Mosteploenergo

Procedure for determination of maximum and minimum coolant and water flow rates at heat stations when selecting heat and water meters. Department of Fuel and Energy Economy of the Government of Moscow, 27.10.98;

SNiP 2.04.0786. Thermal networks.;

SP4110195. Design of heat stations;

SNiP 2.04.0284. Hot water supply.;

SNiP 2.01.0182. Heating, ventilation, air conditioning.;

Rules of heat energy and coolant accounting.;

Rules for the use of thermal energy. PR347001085.;

Technical solutions

Electric equipment

Electrical equipment of the heat metering unit is supplied from the power panel located on the 1st floor.

Supply mains voltage 380/220V with neutral grounding. According to the degree of reliability of power supply, the electric receivers of the metering unit belong to the 1st category.

The design provides for lighting of the installation sites of the heat metering board and primary flow converters using lighting fixtures with incandescent lamps. Lighting control is local.

The design also provides for the installation of a socket with a ~ 220V 50Hz grounding contact near the installation site of the heat metering board.

Supply mains and lighting mains are made by cable with copper residential grade IWG in steel electric welded pipes, open under the basement ceiling.

Anti-vandal events

For anti-vandal measures it is necessary to provide locking of the entrance metal door.

After installation works, the heat meter shall be sealed by the representatives of the heat monitoring bodies. The following heat meter units are sealed:

- cover of the terminal box of the primary flow converter;

- flow transducers and resistance temperature transducers on the pipeline;

- housing of measurement and calculation unit.

Scheduling

To control the hydraulic operation mode of heating and hot water supply systems, it is possible to connect pressure sensors to the IVB, as well as to connect the outdoor temperature sensor. In this case, the sensors are installed:

- on the supply heating pipeline;

- on the reverse heating pipeline;

- on GVA supply pipeline;

- on the GVA return pipeline;

- on CFS pipeline;

- on the exterior wall of the residential building, oriented to the north.

These parameters can be transmitted to the control room, which also receives temperature monitoring data on the supply and return pipelines of heating systems and WAN, as well as measurement and calculation data of the heat meter.

Heat meter provides transmission of current values of heat supply system parameters and static information via serial interface. This accounting system can be used in the complex dispatching of housing stock with the output of parameters to the ODS. The possibility of output to the ODS involves the presence of a computer-based ODS console in the district control room.

An interface converter is used to transmit information from the heat meter to the computer. The interface converter provides a hardware relay of link signals to the interface signal when communicating with a personal computer.

Instructions for installation of equipment

During installation works the requirements of SNiP 3.05 shall be met. 0185; 3.05. 0385; 3.05.0785, as well as SNiP Sh-4-80 "Safety in construction" and fire safety standards;

During installation of pipelines and equipment, tightness and strength of elements attachment shall be ensured;

Before installation make sure that there are seals on the equipment;

Primary transmitters shall be installed in accordance with manufacturer and design instructions;

Thermal resistance transducers KTPTR05 shall be installed according to the design drawings in the places indicated on the wiring diagram;

The measurement and calculation unit is installed in a separate board;

Wires or cables from temperature sensors and the primary transmitter included in the heat meter set shall be laid in steel pipes or metal pipes;

Test interval of heat meter set is 4 years
