District heating substation - Import export

ENERGY SAVING SOLUTIONS Energy needed for heating amounts up to 60% of total annual energy consuption of a given building. Reduction of the energy consuption can be achieved through improvement of the thermal insulation of the building and with improvement of control systems of the heating instalation. Reduction of energy consuption without compromising the comfort of the hated area is a goal wich has been set for HAI Thermo heating control unit. HAI Thermo is an electronic controller for district heating substations, boiler plants and individual boilers. It regulates the water temperature in the system according to: outside air temperature, inside air temperature and timing schedule. The basis of the regulatory function is a sliding diagram. HAI Thermo has four built-in sliding diagrams. Selection of the adequate sliding diagram is determined by the user’s needs and the thermal characteristics of the building.

District heating systems include a centralised energy centre which then distributes the heat through a network of insulated pipes to the buildings which are connected to the network. The network of pipework consists of a flow and return loop which passes each building. Colloide uses local substations in each building to control the flow of water from the district heating pipework loop through each substation and this flow is used to generate heat in the local building. The central energy centres are generally designed to have more than one energy source, which allows the plant operator to select the most cost efficient and sustainable way of providing the energy needed with the energy sources being brought on and off line to meet demand. We design and build the district heating and cooling networks to include the pumps, pipework, thermal stores, instrumentation, control systems, local substations, heat exchangers and communication through a central control system.
