However, there is still relatively little basic information available on this topic, and the relevant standards have not yet been fully developed. Some issues remain unclear, and I hope to discuss them with everyone! 1. Data on the land area and building area required for clean energy heat sources; does this data take into account the fire separation distances required for gas-based heat sources? 2. Data on the capital investment and operating costs per unit for clean energy heat sources. 3. Factors that need to be considered in the design of clean energy heat source stations include limitations on the distance from which water can be drawn for wastewater-based heat pumps, as well as restrictions on temperature and flow rates; requirements and distance constraints related to water extraction for seawater-based heat pumps; issues concerning the pricing of cooling services; and problems related to economies of scale in the actual construction of such projects. There are many such considerations, and I hope that everyone will use this post as a basis for joint discussion! 4. Selection of the specific friction loss for pipes during hydraulic calculations of centralized cooling systems, as well as general empirical data regarding the prevalence of centralized cooling systems, etc. 5. Common types of heating and cooling terminal units in commercial buildings, and the selection of heat load and cooling load parameters for different types of units. These issues are related to the scale of the heat source, as well as to product brands and local energy prices; they are even connected to the internal configuration of the heat source, such as whether heat storage facilities are available or what type of peak-shaving units are used in the energy station. Therefore, it is not possible to provide general statements on these matters. Therefore, I hope colleagues who are specialized in this industry can share their experience and data based on actual projects, so that we can all learn from each other. Thank you! If anyone has encountered similar problems, they can also leave a message to discuss them; I will gather them all together.
