The daily operation and data information protection of modern office buildings cannot be separated from the multiple guarantees of electricity. More emphasis is placed on technology related self use office buildings, ensuring high reliability through dual municipal power supply, important loads through diesel generators, and fire alarm and weak current control systems through UPS equipment. In modern technology enterprises, various information and data are crucial, not only related to the key data of our own enterprises, but also to the information security and data security of many users in the Internet era.
The diesel generator project is essential in the self use office building, and at the same time, the diesel generator project will also be accompanied by corresponding oil smoke emissions, noise and vibration in the self use office building, which will also affect the office experience of employees in the building. For example, according to the load requirements of the design, considering the civil engineering conditions of the building, it is particularly important to choose the appropriate brand for the corresponding diesel generator set.
For the existing project development and management, it is not just a single unit equipment procurement, but should be considered as a complete engineering content, including unit selection, oil supply pipeline setting, smoke exhaust pipeline system, noise elimination equipment, and even subsequent environmental acceptance and property operation, all of which require overall engineering considerations. Let's briefly discuss the bidding and procurement considerations for diesel generator sets.
The purchase of diesel generators is first based on the calculation of the required unit power based on the required electrical load. The higher the power, the higher the price. Before bidding for procurement, it is important to have a clear understanding and pay attention to the relationship between rated power and backup power. In diesel generator sets, the power is generally expressed in kVA or kW.
KVA is the unit capacity and the apparent power. KW is the electricity consumption power and the effective power. The factor relationship between the two can be understood as 1kVA=0.8kW. It is recommended to clearly design the power consumption load requirements before procurement, and it is generally recommended to use effective power kW. Before bidding for procurement, it is necessary to communicate and confirm with the electrical designer, and clarify the unit power of the same concept in the design drawings, technical specifications, and quotation list.
In the process of communication with technology and suppliers, the expression should be based on the same power, and the corresponding equipment should be clearly defined to avoid wasting costs due to insufficient configuration of equipment or excessive unit equipment after purchasing equipment.
Power level of diesel generator set: small diesel generator set 10-200 kW; Medium diesel generator set 200-600 kW; Large diesel generator set 600-2000 kW; Generally, we use large units when building new office buildings for our own use.
The installation site of the diesel generator set should have good ventilation, with sufficient air inlet at the generator end and good air outlet at the diesel engine end. When used indoors, smoke exhaust pipes must be connected to the outside. The outlet of the flue should be reasonably set up to avoid backflow of smoke or thick black smoke affecting the overall operation or employee experience.
After determining the basic power consumption in the design, it is recommended to conduct preliminary technical exchanges with alternative brand manufacturers to ensure that the product lines of the participating units in the quotation can meet the technical requirements. Communicate clearly on the power, select products within the product range that can meet the rated power, and generally consider the need for one in use and one backup.
The selection should also consider the size requirements of the corresponding power intake and outlet shafts, based on the communicated shaft size requirements. Calculate whether the civil smoke exhaust area that meets the requirements of the exhaust duct needs to be adjusted. If it cannot be met, it is necessary to consider whether it is possible to make changes to the civil conditions or whether ventilation equipment can be installed on the existing flue, or to expand communication with brand manufacturers.
