HEAT INTERFACE UNIT TESTING TEST METHODOLOGY


5 TEST METHODOLOGY

The method used for determining thermal performance was in accordance BTS/2 2015 Test Method

for Heat Interface Units.

5.1 UNCERTAINTY BUDGET

Table 5 shows the uncertainty of measurement as defined in Section 4.1, Table 1 of BTS/2 2015. This

information refers to the accuracy of individual measurements. The stability of the test rig complied

with the criteria given in Section 4.2 of BTS2/2015 (see Table 6).

Table 5 Uncertainty of measurements taken from BTS/2 2015

Measured quantity Unit Resolution Uncertainty of measurement

Inlet fluid temperature °C 0.05°C ±0.15°C

Outlet fluid temperature °C 0.05°C ±0.15°C

Volume flow rate l/s 0.01 l/s For flows <0.5 l/s ±2.0% will apply For flows ≥0.5 l/s ±1.0% will apply

Fluid pressure difference kPa 10 Pa ±5% measured value

Electric power W 0.1 W ±1.5 % measured value

Voltage V 0.1 V ±1.5 % measured value

Current A 0.01 A ±1.5 % measured value

Electrical energy kWh 1 Wh ±1.5 % measured value

5.2 TEST TOLERANCES

The permissible deviations from set values taken from BTS/2 2015 are given in Table 6.

Table 6 Permissible deviations from set values taken from BTS/2 2015

Measured quantity Permissible deviation of arithmetic

mean values for the test period from set values

Permissible deviations of individual measured values from

set values

Inlet fluid temperature (primary and secondary circuit)

±0.3°C ±0.5°C

Volume flow rate (primary and secondary circuit)

For flows ≤ 0.3 l/s ±4% will apply For flows ≤ 0.5 l/s ± 2% will apply

For flows > 0.5 l/s ±1.5% will apply

For flows ≤ 0.3 l/s ±5% will apply For flows ≤ 0.5 l/s ± 3% will apply For flows > 0.5 l/s ± 2% will apply

Voltage (V) ±3.0% of measured value ±5.0% of measured value

All instrumentation used during these tests was within the uncertainty budget given in Table 5. The

instrumentation used for the thermal performance tests was connected to a logging system that logged

all the parameters into an Excel file at 30 second intervals. This data was able to be viewed live

during the testing.



5.3 TEST SET-UP

The test was carried out in an environmental chamber. The environmental chamber consisted of an

insulated room with a dedicated supply of temperature controlled water for both the primary and

secondary circuits. The HIU was installed in the environmental chamber. During the tests, the door to

the environmental chamber remained open. To carry out the test, the following instrumentation was

installed on the test rig:

Two in-line electromagnetic flow meters, one on the outlet side of the primary circuit and one

on the inlet side of the secondary circuit

Four Platinum Resistance Thermometers (PRTs), one each on the inlet and outlet of both the

primary and secondary circuits

Two differential pressure transducers, one measuring across the inlet and outlet of the primary

circuit and one measuring across the inlet and outlet of the secondary circuit

Electrical energy meter on the supply lead to the pump

One PRT measuring the ambient temperature in close proximity to the HIU

The water systems associated with the environmental chamber were configured to achieve the design

input parameters. A schematic of the hydronic system is shown in Appendix C.

Each HIU had an integral pump on the secondary circuit designed to circulate the water through the

space heating circuit. The pump on each HIU was factory set to “constant speed” control at setting 1.

This can be seen in Figure 4.

Figure 3 Pump setting



Steady-state conditions were assumed to exist, when all changes and periodic fluctuations of

individual temperatures and volume flows remained within the tolerances given in Table 6. The test

period lasted 30 minutes with data logged every 30 seconds.

To calculate the thermal duty of the plate heat exchangers in the HIU, the following formula is used:

𝑘𝑊 = 𝑣𝜌𝐶𝑝Δ𝑇

Where:

𝑘𝑊 = 𝑇ℎ𝑒𝑟𝑚𝑎𝑙 𝑑𝑢𝑡𝑦 𝑣 = 𝑉𝑜𝑙𝑢𝑚𝑒 𝑓𝑙𝑜𝑤 𝑟𝑎𝑡𝑒 𝑖𝑛 𝑙. 𝑠−1 𝜌 = 𝐷𝑒𝑛𝑠𝑖𝑡𝑦 𝑜𝑓 𝑡ℎ𝑒 𝑤𝑎𝑡𝑒𝑟 𝑎𝑡 𝑡ℎ𝑒 𝑓𝑙𝑜𝑤 𝑚𝑒𝑎𝑠𝑢𝑟𝑖𝑛𝑔 𝑑𝑒𝑣𝑖𝑐𝑒 𝐶𝑝 = 𝑆𝑝𝑒𝑐𝑖𝑓𝑖𝑐 ℎ𝑒𝑎𝑡 𝑐𝑎𝑝𝑎𝑐𝑖𝑡𝑦 𝑜𝑓 𝑤𝑎𝑡𝑒𝑟 𝑎𝑡 𝑡ℎ𝑒 𝑡𝑒𝑚𝑝𝑒𝑟𝑎𝑡𝑢𝑟𝑒 𝑎𝑝𝑝𝑟𝑜𝑝𝑟𝑖𝑎𝑡𝑒 𝑓𝑜𝑟 𝑡ℎ𝑒 𝑡𝑒𝑠𝑡 𝛥𝑇 = 𝑇𝑒𝑚𝑝𝑒𝑟𝑎𝑡𝑢𝑟𝑒 𝑑𝑖𝑓𝑓𝑒𝑟𝑒𝑛𝑐𝑒 𝑏𝑒𝑡𝑤𝑒𝑒𝑛 𝑖𝑛𝑙𝑒𝑡 𝑎𝑛𝑑 𝑜𝑢𝑡𝑙𝑒𝑡 𝑡𝑒𝑚𝑝𝑒𝑟𝑎𝑡𝑢𝑟𝑒 𝑜𝑓 𝑒𝑎𝑐ℎ 𝑐𝑖𝑟𝑐𝑢𝑖𝑡 𝑜𝑓 𝑡ℎ𝑒 𝐻𝐼𝑈 𝑖𝑛 𝐾

The values used for volume flow rate and ΔT were taken as the average over the 30 minute test period.

The electromagnetic flow meters used for testing, measured volume flow rate (l.s-1

). In order to

calculate the thermal duty, the density of the water at the flow measuring point needed to be obtained.

Using the temperature of the water at the flow meter and Table 2.2 on pages 2-4 to 2-6 of CIBSE

Guide C, the density of the water can be determined by interpolating between two temperature points

in the table. The density and specific heat capacity used for each test is given in Table 7.
