The building heat exchange station overview:
The heat exchange station in small heating area division, usually single building as the heating unit, heat exchange station called building exchange station this small, usually arranged in the underground part of the building; building heat transfer station use unit referred to as building units. (Note: a single building (or building) is recommended as a unit, with an area of 2000m2 to 20000m2
The advantages of building heat transfer station:
It can effectively avoid the net two times the heat loss, significantly reduce energy consumption, reduce the workload of hydraulic balance adjustment.
The purpose of the use of building heat exchanger can greatly reduce the difficulty of construction and engineering network.
The purpose of building heating heat exchanger station has small size, strong pertinence, sensitive regulation and fast response and other advantages, can realize heating according to need, system reliability.
The purpose of the reasonable layout, compact structure, small occupation area, less investment.
Classification of building heat exchangers:
Divided into indirect connection and connect directly, indirectly connecting buildings called heat exchanger unit, connecting directly in front of the building known as the mixing unit. The building units are designed, manufactured and tested in the factory, then transported to the construction site and connected to the existing indoor heat supply network, pipelines and water supply pipelines, telecommunication facilities and building power supply.
Building heat exchanger unit:
The building heat exchanger unit is a compact and highly integrated heat exchange unit. The main part of the heat exchange unit buildings include: heat exchanger, circulating water pump, water pump (optional), flow restrictor valve, safety valve, filter, pressure temperature measuring element, heat meter, electric actuator (instead of electric control valve), water treatment equipment, water supply system, control, and communications equipment it is necessary for power supply equipment; locking valve and control box, vacuum degassing machine, spiral cleaner etc..
The building heat exchange unit can be used in a variety of different water treatment and water system (optional), such as water softener, dosing pump, by-pass filter, tourmaline, electronic descaling instrument or microcomputer multi frequency water processor, a water supplement two times net form etc..
Heating, floor heating, air conditioning, hot water and other system building heat exchange unit is suitable for access to municipal or regional boiler room heating, but also can satisfy a set of high and low for the two system, or a set of units for the use of two kinds of heating and hot water.

In front of the building water mixing unit:
In front of the building is two times the mixing unit, measurement, automatic control and data upload equipment such as thermal integration in one station. The main part of the building water unit includes: circulating water pump, valve (valve, check valve, manual balancing valve), filter, pressure and temperature measuring element, heat meter, dynamic balance type electric control valve, control and communication equipment, power supply equipment etc..
The mixing unit is suitable for the two heating, heating station access network or regional boiler room floor heating and air conditioning system in front of the building, and can realize the coexistence of three systems in a two network.
In front of the building water unit is divided into direct mixing type, two mixed type and complex mixing form.
