Modernization and improvement of VRV/VRF systems
Modern technologies in the field of climatic equipment are constantly improving, so modernization of VRV/VRF systems in Tashkent becomes a relevant solution for owners of outdated installations. VRV (Variable Refrigerant Volume) and VRF (Variable Refrigerant Flow) systems are modern climate equipment with variable refrigerant flow, which is widely used in office centers, shopping malls and industrial buildings. Timely updating of components not only increases the efficiency of the system, but also significantly reduces operating costs.
The main areas of modernization that we offer as part of the maintenance of VRV systems:
- Replacement of outdated controllers with modern control systems with advanced functionality and remote access capability
- Integration of VRF systems with a common smart home system or BMS (Building Management System)
- Installation of energy-efficient components to reduce power consumption while maintaining performance
- Replacement of refrigerant with more environmentally friendly and efficient types in accordance with modern regulations
- Implementation of monitoring and diagnostic systems to check VRF system pressure and other parameters in real time
Professional air conditioning service includes a comprehensive assessment of the current state of the equipment and development of individual recommendations for modernization, taking into account the peculiarities of the facility and the client's needs. Our engineers perform a detailed analysis of the efficiency of the existing system before proposing improvement solutions.
Daikin VRV service is particularly in demand for upgrading systems installed more than 10 years ago. Daikin's state-of-the-art technology can significantly improve energy efficiency and ease of control while retaining much of the existing infrastructure, making upgrades cost-effective.
Repair and adjustment of VRV equipment is often accompanied by recommendations for modernization of individual units, which can improve system reliability and reduce the likelihood of repeated breakdowns. Our specialists always offer several options for solving the problem with varying degrees of modernization and corresponding budgets.
As part of an air conditioning service contract, we offer phased modernization, allowing us to spread the financial burden and implement improvements in accordance with the client's priorities. This approach is especially relevant for maintenance of climate systems in offices and shopping centers in Tashkent, where it is important to maintain the continuity of work processes.
Comprehensive diagnostics of multizone air conditioning systems at each scheduled maintenance allows to timely identify components that require modernization and prevent reduction of efficiency of the whole system due to obsolete elements.
How often should a VRV/VRF system be serviced?
Optimal frequency of maintenance of VRV systems in Tashkent conditions is 2-4 times a year depending on the intensity of operation. The minimum recommended schedule includes mandatory pre-season maintenance before the start of the summer period (March-April) and preparation for winter operation (October-November). For commercial facilities with round-the-clock operation of equipment, scheduled maintenance of VRF systems is recommended quarterly to ensure uninterrupted operation and prevent unplanned downtime.
How long does the service take?
A standard service of Daikin VRV or other manufacturers' systems for a medium-sized office (up to 500 m²) usually takes 4-8 hours for a technical team. The duration of VRF air conditioner service depends on the number of indoor and outdoor units, their availability, and the need for additional work such as cleaning of VRF outdoor units or refrigerant refilling. For large facilities, the work can be spread over several days to minimize the impact on work processes.
What happens if you don't do maintenance?
Lack of regular diagnostics of multi-zone air conditioning systems leads to a gradual decrease in efficiency, increased energy consumption by 30-40% and a significant reduction in equipment life. Without timely pressure check in VRF system, the risk of refrigerant leakage increases, which not only reduces performance, but can lead to complete failure of compressors. The cost of overhaul and adjustment of VRV equipment in emergency cases is 3-5 times higher than the cost of regular preventive maintenance.
Can the system be serviced on its own?
Self-maintenance of VRV/VRF systems is not recommended as it requires special equipment, knowledge and authorization to work with high-pressure refrigeration circuits. Unprofessional intervention may cause serious damage and invalidate the manufacturer's warranty. Basic maintenance may include only regular replacement of air filters of indoor units and visual inspection of equipment condition. For professional maintenance of climate systems in offices and shopping centers it is necessary to contact certified specialists.
Is there a warranty on the work performed?
For all types of maintenance and repair work on VRV/VRF systems we provide a warranty from 3 to 12 months depending on the type of service. By concluding a contract for air conditioning service, you get extended warranty obligations and priority service in case of malfunctions. All work performed is documented in a service log with a detailed description of the activities performed and recommendations, which ensures quality control and transparency of service.
