Noac is an organization performing changes in the management system. the organization is shifting to digital mode of marketing. in this case, the staff members and the technicians impart significance in the research report. the technician involves various tasks in terms of customer handling and system functionalities. the website must include details of the ac, their types, installation methods, and testing types. moreover, it must include few more details about the facilities and benefits.

This report consists of several information regarding the testing background of ac such as cooling, heating, and humidity control. moreover, the various types testing methods, identification of the appropriate testing method, their application and performance. on the other hand, it also includes the activities performed to create a new data base and familiarity of the system with the traditional system. The overall reports for assignment help provides an idea of testing methods of the ac and how to conduct it.

Task 1

various types of testing in terms of nqac, they provides a various types of testing methods, it includes,

• air enthalpy calorimetric
• temperature testing
• variable capacity testing discussion air enthalpy calorimetric air enthalpy calorimetric is required for testing the temperature such as cooling and heating. it includes the two methods such as the calorimeter room method and indoor air enthalpy or psychometrics methods.The measurement in terms of energy input to a room is done by calorie metric room method.

Moreover, it controls the temperature by an ac unit (job, & lidar, 2018). on the other hand, it maintains the air temperature inside the room at a constant value. whereas, the constant value is equivalent to the cooling capacity of the ac.

Indoor air enthalpy method it measures the air enthalpy such as air moving in and out of the ac indoor unit. in the case in changing the air enthalpy, it is multiplied by the rate of air flowing is equal to the cooling capacity of the indoor ac unit. test temperature in this case of ac installation, testing the temperature is essential for the identification of outdoor air temperature. moreover, it also includes testing the loading system, and average weight of the outdoor air temperature (mohanraj et al, 2012). these are used to measure the performance of the load system and also in calculating the efficiency metrics. it is divided into two segments, such as full load test conditions.

It is the method that includes the testing of air cooling condensers that works by evaporating the condensate. part load test conditions in this case, the capacity of humidification falls off. it is also termed as seasonal efficiencies that are required to measure the efficiency. the measurements are particularly done in part-load and full- load capacity. it controls the cooling and heating load by using the relative cooling and heating load hours.

Variable capacity testing in the case of variable capacity testing, it includes the demands of heating and cooling loads of an ac. it maintains proper cooling inside the room. moreover, it has the ability to dehumidifying. it also includes the compressor speed. the main purpose of ac compressor is to control the refrigerant under the pressure in the system. In this case, change in pressure takes place. the low pressure has converts to high pressure gas (prabakaran et al., 2022). on the other hand, the compressor speed determines the rate of refrigerant flow. the motor capacity and frequency varies in this case. the motor speed decreases with increase in capacity output. identification on the type of testing the type of testing which is applicable for the new nqac is temperature testing. in this case, temperature testing is essential for better maintenance of ac performance and servicing. it includes the loading system and weight of the outdoor air temperature. it overviews the overall performance and efficiency of the system. in terms, nqac includes the methods in their installation techniques to improve their service towards their potential customers and new customers as well. as the organization has shifted to digital mode it is necessary to provide temperature testing (dias et al., 2016). it is one of the unique features that nqac must include their management system. it deals with the loading system such as cooling and heating procedures. moreover, it is one of the servicing methods that include checking the performance and efficiency of the system. moreover, it supports the organization in getting a separate customer base. by providing the necessary facilities and meeting the customers’ demand will lead the organizational development digitally.

Task 2

Activities performed to create the database the responsible technician, users, and analysts are required to prepare the new database. The databases are mainly collected from the organizational growth report, feedback report, and other organizational data resources (zhang et al., 2014). in the end, the database is stored in the cloud system database. it is a significant way to store, secure, and protect the data. the website must be encrypted with the cloud computing systems.

Task 3

The similarity in the new system there are still some features and functionalities in the existing system, that are similar to the new proposed system. however, these are essential to evaluate and document to determine all the appropriate system features that are effective and sustainable in nature (blum et al., 2019).
however, this is the responsibility of the project manager, to document and supervise all the system similarities, which must be unchanged in further development procedures as well. the previous system was manual with different business process complexities such as poor cost and time effective
time management.the particular similarities are,

• core supply chain system and management process
• billing and packaging
• team culture and team distribution
• research and development system


All of these similarities come with particular business advantages. these advantages can be implemented through effective management and critical analysis of the current business scenario

with the proposed system technology. the advantages are,

• better business management and documentation
• better finance management and resource supply maintenance
• shorter processing time
• advanced database management and analysis
• better market analysis and report evaluation
• effective business process improvement with digital technology implementation


organizational disadvantages are also associated with these business system similarities. these must be considered and evaluated accordingly, to avoid the negative consequences. this is the responsibility of the project manager, to document and evaluate these disadvantages accordingly. this will not only lead to effective precaution but also will improve the business system and management.

Task 4

System deployment options

The system development can also be categorised into different system development options such as agile development, lean development, etc. these two are the major development methods or options available for the project. this depends on the compatibility and effectiveness of the business model.

Agile management or development option has the idea of equal and effective work distribution between the teams with effective engagement. it also provides better flexibility and innovation in the development phase (shah et al., 2013). though, it also causes different complexities such as poor time and resource management for continuous system changes with feedback analysis. in spite of that, the lean development option will be the most effective and appropriate in this case, as the system should follow the appropriate development strategy and planning. this is only the developer to call site band quantity analysis of different business requirements and system analysis.

this is also effective for resource management and eventual results (goetzler et al., 2016). overall, this analysis can establish that the lean management option will be most effective as a development option for the information system technology of the organisation. application of the option in the application phase, the project manager is responsible to develop appropriate and most effective planning that can develop the proposed system technology. in the next phase, open analysis and different reports who is implemented and the development phase will be started. The management authority and project manager will motivate and supervise the whole department for better analysis and further changes (if required). finally, the system will go through a proper testing procedure and feedback analysis that can improve the quality and service in a real-life business scenario.


To conclude, the testing method impacts a major significance in ac installation. the organization nqac provides a unique feature of temperature testing methods that can gradually increase the market demands. the facilities provided by the organization support gaining potential customers in the future. it helps in maximum registration and booking of products gradually. as the organization is recently shifting to a digital mode of marketing, it is essential to analyze the advantages and disadvantages of the conduction of the new system. developing the testing method leads the organization to follow the market trends, market demands, and customers’ requirements.
