TVRF Heat Pump can realize a combination of 3 outdoor unit modules connecting with as many as 61 indoor units. it’s especially applicable for business building or hotels
The TVRF Heat Pump system is designed without liquid receiver and the excess refrigerant is stored in the piping, which can minimize the refrigerant charging volume and enhance the control accuracy of refrigerant.
The TVRF Heat Pump system has 2 modes for energy saving, which can be chosen to meet different electricity demands.
In auto energy-saving mode, the system will self-adjust parameters according to the operation status, thus to lower the cost of electricity. Up to 15% of energy can be saved.
In compulsory energy-saving mode, the system will limit power output forcibly. Up to %20 of energy can be saved.
Advanced intelligent defrosting mode is adopted. Tosot advanced intelligent defrosting mode will choose the best defrosting way according to outdoor temperature and operation status to realize intelligent defrosting, effectively improving heating effect and performance. While in traditional defrosting mode, timing defrosting is adopted, which not only affects comfort but also reduces energy efficiency.
Traditional Defrosting Mode
Tosot Intelligent Defrosting Mode
• When total load demands more than 75% of a running system’s capacity, one more unit will automatically start;
• When total load demands less than 40% of a running system’s capacity, one unit will automatically shut down;
• Therefore, each unit shares 40%-75% of the total load.
• Experiments show that an air conditioner costs the least energy when it’s operating within 40%-75% of its capacity.
• Output of Optimal Portion to Ensure Highest Efficiency
The best heating or cooling performance can be realized in the most energy-saving way. DC inverter compressor and DC inverter fan will also be operating in this way to ensure high efficiency.
• Heat exchange loop can control the first subcooling process of heat exchanger. Subcooling degree can reach 11ºC.
• Subcooling loop can realize 9ºC second subcooling to guarantee cooling and heating performance.
Through setting temperature lower limit in cooling or dry mode, and setting temperature upper limit in heating, 3D heating or heat supply mode, the system is able to operate in a smaller temperature range so as to achieve energy saving.
The TVRF Heat Pump system has a wide range of working conditions. Whether it’s in a cool winter or a hot summer, normal operation is guaranteed with the least noise, making users feel more comfortable.
• Quiet at night
The system can record the highest outdoor temperature. At night, the system will automatically turn to quiet mode. There are 9 quiet modes which can be set according to actual needs.
• Quiet in compulsion
The system can also be set in this mode to ensure low noise as long as it is operating. Noise is as low as 45dB(A).
• Quiet Control
1. Optimized Bossing Design After many times of CFD tests, a new fan bossing structure has been developed to reduce vibration of fan during running. Noise can be reduced by 3-5dB(A).
2. Aerodynamics 3D Axial Fan Compared with conventional fan, it can increase air volume by 12%, improving efficiency as well as lowering noise.
• Quiet Indoor Unit
The indoor unit of the TVRF Heat Pump system also adopts DC inverter motors to realize stepless regulation. According to indoor temperature or people’s actual needs, users can set this mode through wired controller. Noise is as low as 22dB(A).
• Fast Start-up in Heating
DC Compressor is first started to avoid too much electric current. Inverter compressor can operate in high frequency once starts up, so as to produce more heat.
• 7 Levels of Indoor Fan Speed for Option
Indoor fan speed can be set in 7 levels by wired controller. They are auto, low speed, medium-low speed, medium speed, medium-high speed, high speed and turbo. When the wired controller is on, press “FAN” button to set indoor fan speed circularly as below:
Through 10 years of research and development, Tosot TVRF Heat Pump has been further upgraded to a high level from electrical components, mechanical parts, control technology to communication technology.
First-stage oil separator adopts a filtration expansion valve with separation efficiency of 98%; Second-stage oil separator will separate the remained 2% refrigerant oil with separation efficiency of 95%. General oil separation efficiency reaches 99.9%.
• New Oil Return Control
Tosot new oil return control technology effectively controls system oil return and oil storage status of each compressor, which greatly improves the operation lifespan of compressor.
• Specialized Compressor Oil Storage Control
The system applies specialized compressor oil storage technology, which can control the lowest oil level for compressor operation.
• Oil Balance Between Each Module
Based on the actual status of each module and compressor, the system can regulate compressor’s operation and realize oil balance of each module.
• Oil Balance Between Each Compressor
Refrigerant is taken into the compressor by the suction pipe and then runs through the cooling Discharge system. It can control the pipe oil level and minimum oil volume required by each compressor so as to realize oil balance between each compressor.
• Modules 8h rotation operating
The operating priority sequence of the outdoor unit modules will be changed without restart when the system accumulatively operates for 8 hours, which can maximize the service life of the system.
• Emergency Function
The TVRF Heat Pump system can realize a combination of 3 outdoor unit modules. When error is occurred to one of the modules, the others will perform the emergency operation to sustain the air conditioning.
The unit can be turned on or off by inserting or removing the key-card. When the key-card is removed, the system can remember all the setting and stop operation. When the key-card is inserted back, the system will be under standby mode or operate according to the status before removing key-card. It is well suited to hotels, restaurants, etc.
