heat transfer equipment,
industrial heat exchanger
Usually in the ground heating area, the need for large area subdivision into a small block control, or a set of residential, there are multiple functional rooms, need to be controlled separately. At the same time, the floor heating system is affected by the hydraulic characteristics, the warm coil is limited to a certain length. This requires the same ground heating area or the same set of residential heating room is divided into multiple loops, and each loop and need to be shut down or flow adjustment. Points, the collector in the low-temperature hot water ground radiant heating system plays such a role. It is the first side of the heating pipe water according to the needs of the building heating distribution, to ensure that the regional branch loop flow to meet the heating load needs. At the same time, but also the branch of the flow of water collection, and input heating back to the main pipe to achieve the cycle of operation. On the other hand, due to the various functional areas of the building (room) need to heat on demand. In order to facilitate the regulation and control, the water separator and the collector of the branch loop configuration of the valve, the valve to bear the flow distribution and regulation tasks. The warm structure system is buried buried heating end, most of its structure is buried in the concrete structure layer, only sub-catchment exposed on the outside.
2. Principle & Function
Central air conditioning set of water dispenser to the distribution of water to the role of the distribution, the water collector from the shunt, the loop pool the role of water flow. The manifold and the sump are set up to facilitate the connection of the parallel pipes of each water loop, acting as a pressure equalizer to distribute the flow evenly. In order to prevent the obstruction of the water piping system and ensure the normal operation of the equipment and valves in the waterway system, a filter should be installed in the piping system to remove debris from the water. Usually the filter should be installed in the suction pipe of the pump and the inlet of the heat exchanger.
|Generally in the two-way supply of air conditioning systems, are set with a set of water, used to achieve the system of water flow distribution and circulation. In the selection of the model of the water separator, the standard that is usually considered is the diameter and length of the cylinder|
|What type of selection should also be considered in accordance with these two aspects.|
|In general, the diameter of the main cylinder of the manifold should be selected at the flow rate (0.5-1.0 m / s) at the total flow rate and should be greater than twice the maximum nozzle opening diameter; the main cylinder of the manifold The length should be based on the number of systems that collect water pipes|
|And the distance between each two branch pipes should be 120 mm (outer diameter spacing).|
|Set the water pipe diameter D detailed determination method:|
|1. According to the cross-section flow rate to determine the diameter D: sub-cylinder flow rate by 8-12m / s; water divider and water collector by section flow rate of 0.3 ~ 0.7m / s calculation.|
|2. According to the empirical formula to determine the diameter D: D = (1.5-3) DMAX (DMAX branch diameter).|
|① set between the water collector plus the pressure difference between the bypass valve and bypass pipe (DN50 generally take the diameter).|
|② water dispenser should be set up on the thermometer.|
Functional structure point of view. There are three types of water dividers: basic, standard and functional. Basic type: composed of water mains and water mains. A ball valve is provided at each branch port of the branch water main pipe, and a manual exhaust valve is provided on the branch water main pipe. The basic type of water separator does not have the flow regulation function. Standard type: standard sub-collector structure with the basic type of the same, but the main pipe on the flow control valve replaced by the flow control valve. The manual exhaust valve on the two main pipes is replaced by an automatic exhaust valve. Standard sub-sumps can adjust the flow rate of each loop, and even the flow of luxury standard sub-sump can be adjusted to achieve artificial intelligence. Functional type: functional sub-sorter in addition to all the features of the standard sub-catchment, but also has a temperature, pressure display, automatic flow control function, automatic mixing water heat transfer function, thermal metering function, indoor partition temperature automatic control Function, wireless and remote control function.
|1. Set the water separator should be installed before the start of the installation of heating pipe. When horizontal installation, the general should be installed in the water separator, the collector installed in the next, the center should be 200mm, the center of the catchment from the ground should be not less than 300mm. When the vertical installation, the sub-catchment at the lower end of the ground should be not less than 150mm.|
|2. The location should be located in the easy control, maintenance, and drainage pipes. Such as toilets, kitchens and so on. Should not be located in the bedroom, living room, not even in the storage room, cabinets. In addition, can also be set in the indoor pipe wells.|
|3. For semi-super-layer of the room, set the water separator should be located in the high or high, low area were set: for the duplex structure, should be located in the upper and lower corresponding trunk on the trunk.|
