IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report, Date: 06/2011 Installation period (days) 90 90 60 60 60 30 30 33 3 5 20 3 15 15 4 10 plant 1 plant 2 plant 3 plant 4 plant 5 plant 6 plant 7 plant 8 plant 12 plant 13 plant 14 plant 15 plant 16 plant 17 plant 18 Average Figure 9: Installation period of plants The number of people involved for installation for the evaluated plants shows that for most of the plants less than five people were necessary (see Figure 10). Also this can be used as an indicator for pre-engineered systems to avoid misunderstandings and time delay during installation due to the amount of involved people and companies. People involved in installation 18 20 20 3 2 6 3 3 4 3 2 5 3 2 8 3 7 plant 1 plant 2 plant 3 plant 4 plant 5 plant 6 plant 7 plant 8 plant 10 plant 12 plant 13 plant 14 plant 15 plant 16 plant 17 plant 18 Average Figure 10: People involved for installation In seven of the evaluated plants time delays during installation (see Figure 11) were recorded. page 11
IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report, Date: 06/2011 The reasons for such time delays mentioned are as follows: caused by plant owner: negotiations and ordering is regulated by public law and took quite long (delay 3 month) pump didn’t work caused by discrepancies with installer caused by installer and subcontractor of installer (two weeks) different time period of material delivery difficulties in finding the desired pumps water damage caused by poorly compressed pipes The list of reasons mentioned above show that most of the problems occurred were not particularly related to solar heating and cooling technology but to HVAC technology in general. 5% 56% 39% yes no no answer Figure 11: Delays during installation In Table 1 the main problems mentioned during installation are listed as well as the solutions and the time for solving the problem. Pre-designed control strategies as well as quality standards for piping would have avoided most of the problems mentioned. page 12
