Integration of buffer containers into the circuit:

From hydraulic mopures to buffer containers, the main supply and reverse pipeline is laid.

For efficient operation of the system, the correct connection of the input and output pipes was provided, which provides uniform filling of containers with a coolant.

Three -way valves are used, which automatically regulate the flow of coolant between buffer containers and the main heating contour.

Hydraulic balancing:

In order to avoid hydraulic boards and stable operation of the entire system, hydraulic balancing of the contours was performed.

The air vents were installed in key points for removing air from pipelines and preventing the formation of air plugs.

Thermal insulation:

All trunk pipes, connecting hydraulic boards and buffer containers, insulated with high -quality insulation to reduce heat loss.

Particular attention is paid to the places of joints and threaded connections, which are additionally treated with sealants to prevent leaks.

After completing the installation of pipelines and connecting to buffer containers, The system was ready for testing. The cascading connection of hydraulic moil in combination with buffer tanks allows you to evenly distribute the load, maintain a stable temperature in the system and increase its effectiveness.

6. Connecting indirect heating tank Raymer DHWP 300L

After completing the installation of two Raymer hydroelectric mowers and their integration with buffer containers, The next step was the installation and connection of an indirect heating tank Raymer DHWP 300L.

7. Distribution of heat in the room

For the effective distribution of heat in the production room, it was used A set of HC45-3S air-polling device with a rotary bracket and a three-stage fan speed regulator.

The device provides the supply of warm air using a fan, which drives the air through the heat exchanger, heating. Thanks to the rotary bracket, the possibility of adjusting the direction of the flow of warm air was ensured, which allows you to effectively warm as the main work area, and remote sections of the room.

A three -stage regulator allows you to choose the operating mode of the fan depending on the temperature conditions in the room – from the minimum to maintain a comfortable temperature to maximum for rapid heating after long breaks or opening the gate.

As a result of the installation of this equipment, uniform distribution of heat throughout the room was achieved and the energy efficiency of the system was increased.

The heat transfer between the buffer containers and the HC45-3S air-polling device occurs using a water coolant, which circulates in the closed circuit of the heating system.

Buffer containers accumulate heat, which is generated by heat pumps. From there, the coolant is supplied to the heat exchanger, built-in in the HC45-3S air-feeding device. In the heat exchanger, hot coolant transfers heat to the air, which the device fan drives through the ribs of the heat exchanger and distributes in the room.

After heat selection, the cooled coolant is returned back to the buffer capacity for re -heating. This process takes place continuously, providing stable temperature and efficient use of accumulated energy.

Thus, buffer containers act as a heat source, and accessories HC45-3S – In the role of an effective distributor of this heat in the room.
