The controller is designed to control Ground Heat Exchangers (GWCs) by controlling throttles and valves with actuators or fans.\u003c\/p\u003e\u003cp\u003eThe \u003cb\u003eIB – Tron 3100GHE\u003c\/b\u003e series allows you to control passive heating and cooling processes. It intelligently selects the heat\/cooling source taking into account three different temperatures.\u003c\/p\u003e\u003cp\u003eProfessional and intelligent controller for controlling systems where you should choose a source of heat or cold from two different sources while protecting the building from excessive cooling.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePrinciple of Action:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThe controller is designed to control the process of heating and passive cooling of installations equipped with two different heat\/cooling sources. A practical example of such a system is the ventilation system equipped with a Ground Heat Exchanger (GWC).\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGround Heat Exchanger\u003c\/b\u003e is a device designed for ventilation of a building, with the help of which natural renewable energy can be obtained from a small depth of the ground. The idea of the device is based on the fact of existence at a depth of 1 to 4 meters of almost constant ground temperature throughout the year. In our climate zone at this depth the ground temperature is approx. +10°C (+\/- 1,5°C). In fact, GWC is situated very shallowly, sometimes even above the ground, in the case of high groundwater. However, thanks to a special design, GWC foundation is simulated at a depth of 5-6m below the surface of the earth.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePassive cooling:\u003c\/b\u003e Hot outdoor air is drawn through the intake. Then, flowing through the GWC, it releases excess heat energy into the cool ground - thereby cooling down. The pre-cooled air is directed to the ventilation unit, which can subject it to another heat treatment or direct it to the rooms.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePassive heating:\u003c\/b\u003e The principle of operation is exactly the opposite of its operation with passive cooling. The cold air flowing through GWC warms up from the warmer ground.\u003c\/p\u003e\u003cp\u003eAt different times, the outside temperature is more favorable than after passing through GWC. E.g. During a warm and sunny winter day, the outside temperature is higher than after passing through GWC or during a summer night, the outside temperature is lower than after passing through GWC. Then the external air should be sent directly to the air handling unit, bypassing GWC.\u003c\/p\u003e\u003cp\u003eThe GWC described is of tubular, gravel or diaphragm type. The external air is directed to the ventilation unit by GWC or directly by means of air dampers with an actuator, e.g. type IB-Fxxx (available on other offers).\u003c\/p\u003e\u003cp\u003eSince in most cases the resistance to the air passing through GWC is much greater than the resistance to the external air drawn directly, it is enough to use only one throttle on the pipe supplying directly to the external air. Opening this throttle will cause air to be drawn directly from the outside. Closure of air intake by GWC.\u003c\/p\u003e\u003cp\u003eIn situations where the resistance to direct air is as high as the air directed by GWC or the expected resistance is not unambiguous - two dampers operating alternately (one closed, the other open) should be used.\u003c\/p\u003e\u003cp\u003eIn the event that GWC resistance is significant, it may be necessary to use an additional GWC booster fan.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eExample Scheme of Operation of Pipe and Gravel GWC:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eExample of connection with one air damper:\u003c\/p\u003e\u003cp\u003eExample of connection with one air damper and an additional booster fan:\u003c\/p\u003e\u003cp\u003eExample of connection with two throttles operating alternately:\u003c\/p\u003e\u003cp\u003eAnother type of GWC is glycol GWC. Its operation consists in the fact that the air is not directed underground and is not heated \/ cooled directly and this is done indirectly by an exchanger mounted on the pipe supplying air to the ventilation unit. Cold\/heat is received from the lower source which can be the ground through the system of vertical or horizontal pipes buried in it. After switching on the circulating pump, energy is taken away from the ground and put into the air by an appropriate exchanger.\u003c\/p\u003e\u003cp\u003eThe lower source can also be an efficient deep well, which will work as a source of cold, but will not be an effective source of passive heating.\u003c\/p\u003e\u003cp\u003eThe IB-Tron 3100GHE controller selects the optimal heat source for cooling and passive heating – it selects whether the air is to pass through GWC or is to be introduced directly from the outside by the appropriate exchanger.\u003c\/p\u003e\u003cp\u003eThe lower source can also be an efficient deep well, which will work as a source of cold, but will not be an effective source of passive heating.\u003c\/p\u003e\u003cp\u003eThe logic depends on the current season. The summer and winter seasons can be set permanently or change automatically based on the average outdoor temperature of T2 (if this sensor is connected).\u003c\/p\u003e\u003cp\u003ePassive heating is implemented in the winter season – a warmer source is selected.\u003c\/p\u003e\u003cp\u003eIn the summer season, passive cooling is implemented – a cooler source is selected.\u003c\/p\u003e\u003cp\u003eWhile in the case of the winter season and the implementation of passive heating there is no risk of overheating the room, in the case of the summer season during the implementation of passive cooling there is a real risk of too much cooling of the room. Therefore, the driver allows you to enable appropriate protection.\u003c\/p\u003e\u003cp\u003eIf the above-mentioned protection option is active and the internal temperature (measured by a built-in temperature sensor), in the summer season it is below the minimum temperature, a warmer source is selected to protect against excessive cooling of the room.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eNote:\u003c\/b\u003e If the protection function against excessive cooling is active, the controller should be installed in a reference room where the prevailing temperature is representative of the entire building. Alternatively, the controller should be placed in a room where too much cooling is burdensome for building users (e.g. bedroom).\u003c\/p\u003e\u003cp\u003eThe T1 temperature sensor is placed in the duct and indicates the temperature of the input air to the ventilation unit.\u003c\/p\u003e\u003cp\u003eDue to the specificity of GWC construction, it is not possible to directly determine the temperature of the input air to the ventilation unit after passing through GWC without its prior commissioning. Therefore, if the currently selected source is intake (external air directly - P1), it is necessary to select the source P2 (start GWC) from time to time for testing purposes to determine what parameters the air will have after passing through GWC (in the case of glycol GWC after switching on the circulation pump). Only after the GWC test work is completed, the T1 temperature is properly measured, which is taken into account when selecting the source.\u003c\/p\u003e\u003cp\u003eThe time interval of how much GWC test should be performed to determine the correct comparative temperature is defined as the \u003cb\u003etest break P2.\u003c\/b\u003e GWC test break is expressed in minutes. Its value depends mainly on the type and size of GWC and more precisely on how often thermal conditions in GWC can change. In typical GWC single-family homes, this value is 90 minutes.\u003c\/p\u003e\u003cp\u003eThe time that determines how long the GWC test is to take place after which the proper measurement of T2 temperature will take place is defined as the \u003cb\u003etest period P2.\u003c\/b\u003e It is expressed in seconds.\u003c\/p\u003e\u003cp\u003eIts value depends on the type and size of GWC, the distance and accuracy of ventilation duct insulation between GWC and the T2 sensor. The P2 test period shall be set empirically or the corresponding calibration function shall be invoked. In typical GWC single-family homes, this value is 120 seconds.\u003c\/p\u003e\u003cp\u003eTypically, the second source is intake (direct air supply from the outside). If the T2 sensor is connected, which indicates the external temperature, it is considered as comparative to the selection of the best source.\u003c\/p\u003e\u003cp\u003eFor optimal operation of the installation in the intake\/GWC system, we recommend connecting an external T2 sensor. However, there are cases when connecting the T2 sensor is difficult or unnecessary.\u003c\/p\u003e\u003cp\u003eThe choice of source is based only on the T1 sensor and the following parameters:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003etest break P1;\u003c\/li\u003e\n\u003cli\u003ethe P1 test period;\u003c\/li\u003e\n\u003cli\u003etest break P2;\u003c\/li\u003e\n\u003cli\u003ethe P2 test period;\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe parameters of test break P1 and test period P1 are analogous to those described above related to P2 output (GWC) and concerning P1 output.\u003c\/p\u003e\u003cp\u003eIf the test period P1 is 0 (default value), it means that the temperature for comparison is taken directly from the T2 sensor. Otherwise, the temperature to be compared is taken only from the T1 sensor after the test work of the P1 and P2 devices.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eNote:\u003c\/b\u003e In order to ensure the correct operation of the controller, the test break should always be greater than the test period for the source.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eNote:\u003c\/b\u003e The P1 test period and the P2 test period are also the minimum time for which a given source must work. This means that after switching the source to P2, the time equal to the P2 test period must elapse in order to change the source to P1.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eExamples of Action: T1 and T2\u003c\/b\u003e sensor\u003c\/p\u003e\u003cp\u003eTypical GWC installation and external intake - direct air extraction from the outside bypassing GWC.
