The time parameters for the test procedures are given in the informative Annex A. 5.2 Testing procedures Test principle This standard covers the test o

35、f a terminal control loop as shown in Figure 1. The temperature in the room is measured by the temperature sensor of a controller which commands then the HVAC terminal system in the room, via an actuator e.g. actuator/valve combination for water systems. PD CEN/TR 15500-2:2016CEN/TR 15500-2:2016 (E)

36、 9 Figure 1 Example for Control loop for HVAC terminal systems The test of this controller is carried out by emulation technique in transient state and the real controller to be tested is implemented in a simulated environment with the room (dynamic model of the heat and mass transfer) and the HVAC

37、system (Figure 1). The room temperature is finally used to assess the performance of the controller. In this approach, the sensor as well as the actuator can be real or simulated. The test procedures and parameters are described in the following sections. 5.3 Test parameters 5.3.1 Temperature parame

38、ters Tests are conducted by simulating three periods of 20 %, 50 % and 80 % load conditions for HVAC emitter during heating and cooling tests. The variation of the internal gains in the zone presents also three periods: 0 %, 30 % and 60 % of the load. Following these variations of the load and inter

39、nal gains, six periods are defined: PD CEN/TR 15500-2:2016CEN/TR 15500-2:2016 (E) 10 Table 2 Definition of the variable test parameters Period Thermal state of the zone Internal gain Heating load Cooling load P1 overshoot 0 % 80 % 20 % P2 transient P3 overshoot 30 % 50 % 50 % P4 transient P5 oversho

41、s The test is split into 6 periods to evaluate the zone controllers performance at three load conditions, when the controller output is in the process of stabilizing (following a change in load condition) and when the output is considered stable (after time period T1) as shown in next table. The per

42、iod T1 is defined in order to avoid the overshoot of the controller. The period T2 is defined in order to qualify the performance of the controller associated to a transient state of the building (zone) thermal behaviour (Table 4).

47、idered cases Figure 3 Control Accuracy for heating (CAH) In the first case CSD -CV 0, the user will shift the setpoint upwards in order to avoid that there are zone temperatures below the comfort region CR. In consequence, the average room temperature will be CV higher than the original setpoint, i.

48、e. the lower limit of the comfort region CR. Regarding the energy consumption we get that the control accuracy CAHis equal to CV. For the others cases, the approach is analogous.
