COMPACT HEAT EXCHANGER – KL-HP series  Pressure independent heat exchanger station

Heat transfer stations are designed for systems with a primary heating medium of hot water at a temperature of 140°C and pressures up to 2.5MPa when this connection is preferred at the request of the maximum cooling around time primary heating water.

This arrangement allows the hot water pressure to separate the primary and secondary sides to ensure the independence facility for distribution networks heating (DH). In this connection method is first primary heating water heat exchanger UT. After the transfer of heat is introduced into the first stage heat exchanger TV where cooled cold water inlet according to the current operation to a temperature of about 30°C. The required temperature of TV is subsequently achieved transvering in the second stage of primary heating water with the original parameter. An important parameter for direct hot water, the maximum hardness of cold water up to 12°dH. If the hardness is higher it is recommended more frequent cleaning of the heat exchanger TV. We also recommend hot water solved in combination with buffer storage tank or to align the output temperature TV.



FUNCTIONAL DESCRIPTION

The primary heat transfer fluid enters the station through the isolating valve, strainer and distributed through control valves into the plate heat exchanger UT and TV. Control valves with actuators with safety features ensure temperature control circuit UT and TV. The primary heating medium passes in plate heat exchangers secondary side. Return the primary heating water cooled heat transfer from the UT is introduced into the plate heat exchanger TV, where the cools. Despite the heat meter, differential pressure regulator and shut-off valve goes back to DH. In the secondary heat exchanger UT heating water is heated to the desired temperature over a shut-off valve output from the transfer station. Secondary hot water circulation ensures electronically controlled circulator. UT system is protected against illocution pressure relief valve mounted in the premium location for heat. The expansion of secondary heating water is captured in the expansion tank. Adding water to the secondary heating system is designed from the primary return pipe assembly through the armatures including measuring up volume. TV is prepared by heating and circulating cold water. Circus-lace TV enters the headed through the isolating valve, strainer, circulation pump and check valve. Cold water enters the head end through the isolating valve, strainer, check valve and water meter. Before entering the heated medium to the heat exchanger is fitted with a fuse-ing valve. In exchanger TV cold water (mixed circular and cold water) is heated to the desired temperature via the isolating valve enters the pipe of the supplied object. For leveling of temperature differences TV and set optimum operating values of the control valve, we fitted stainless steel buffer tank.

Station Control Stations can be mounted control technology to the extent of the customer's choice. Simple controllers provide fully autonomous operation of the stations, including the choice of several time programs, setting equitherm dependencies with limited communication with the dispatching center. Programmable controllers offer a wide range of compact control at substations. Well-chosen programs can be up to optimize operation of the stations. Programmable controllers allow two-way communication with the control center, traffic monitoring, reporting, emergency situations, etc.

DIAGRAM diagram and used components can be replaced by the customer. Stations are supplied without pipe insulation that can be reordered, possibly in the plating compact. For the less accessible places it is possible to produce an atypical involvement and adapt best compact a defined space. Overall design of substations, including drawings, it is always consulted with the chief engineer and the client.
