Direct-connected heating equipment | high-rise building heating equipment

High-rise building heating equipment is a new technology product developed by our company. It directly connects the high-rise building's high-zone heating system with the low-zone heating system. Compared with the traditional high-rise building heating system, it does not require a heat exchanger and does not have a special boiler for the high zone. , without a water tank, the equipment directly pressurizes the heat medium water supply to the high zone, and at the same time decompresses the return water in the high zone and directly connects it to the return water in the low zone, which not only avoids a large amount of heat loss in the heat exchanger system, but also avoids double Open water tank systems cause severe corrosion to piping equipment. High-rise building heating equipment provides us with a heating system with simple structure, low equipment investment, high thermal efficiency and fully automatic operation. With the continuous increase of high-rise buildings in our country, this equipment has gradually become the first choice equipment for high-rise building heating systems and has a wide range of applications. prospect. Scope of application:
High-rise buildings require zoned heating systems (new construction, reconstruction and expansion).
High-rise buildings require zoned central air-conditioning water systems.
The multi-story building is located at the end of the heating network, and the pressure difference between the supply and return water is too small to ensure normal flow of the heating system.
In the same heating network, the terrain height difference is too large, and the multi-story building located at the highest point cannot get the heating demand.
Equipment features:
Power saving of more than %%
Make full use of the original pressure of the municipal thermal pipe network, and through intelligent frequency conversion technology, continuous or scheduled speed adjustment operation can be achieved. Save investment by more than %
Directly connected in parallel with the municipal heating pipe network, saving high investment in civil construction of the machine room, no need for softened water treatment equipment, special water tank expansion tank for constant pressure water replenishment unit, etc., saving a lot of equipment investment.
Energy Saving
Due to the elimination of the heat exchange link and the addition of an automatic water mixing system, the thermal efficiency is close to % and the thermal energy utilization rate is increased by %%. At the same time, the investment in heat dissipation facilities in the heating area is reduced and the heating effect is good.
Highly intelligent, advanced control system, using intelligent interface control system, simple operation, beautiful interface, on-site display of relevant parameters and operating status, enabling remote and wireless monitoring.
Initial investment savings: Conventional heating methods require the construction of heat exchange stations, and the cost of base station construction ranges from hundreds of thousands to several million. This method not only requires large construction funds, but also causes heat loss and unnecessary energy. waste.
Stable operation: The high and low zones do not interfere with each other. The heating system pressure and flow in the high zone are conveniently regulated. Different operating conditions can be determined according to actual needs. Advanced technology and high-quality guarantee equipment can operate stably for a long time.
The equipment occupies a small area and the integrated unit design can be easily installed in the equipment room without occupying other areas in high-rise buildings.
It has a wide range of uses and is not only suitable for new construction projects, but also for grid-connected renovations. The application of this equipment does not require any changes to the heating system in the building.
