Kolant EVI Inverter Heat Pump Core Technology and Working Principle
EVI Solution for Super Cold Area winter heating, summer cooling and domestic hot water.
Enhanced Vapor Injection (EVI) compressors, as a patented technology of the new generation of scroll compressors, are characterized by their core innovation of further improving compressor efficiency by optimizing the injection of refrigerant at the intermediate pressure stage. EVI compressors draw in some intermediate-pressure gas through an intermediate-pressure suction port, mix it with partially compressed refrigerant, and then re-compress it. This process achieves the function of two-stage compression in a single compressor. This technology not only increases the flow rate of refrigerant within the condenser but also expands the enthalpy difference of the main circulation loop, significantly enhancing the efficiency of the compressor.
Kolant EVI Tech Significant Features and Energy Saving Effects
The remarkable features of enhanced vapor injection compressor include its excellent energy-saving effect. In the cooling mode, its average energy efficiency ratio is as high as 3.58, while in the heating mode, this figure is increased to 4.32, and the average energy efficiency ratio of cold and hot is also 3.95, both of which are at the leading level in the industry. These excellent performances significantly reduce the operating cost of enhanced vapor injection compressor and bring remarkable energy-saving benefits to users. In addition, enhanced vapor injection technology has greatly improved the heating capacity of the compressor in cold environment. The series products can heat stably in the temperature range of-25 C ~ 30 C, and this breakthrough achievement leads the multi-line technology to enter the era of "strong cold and heat". Kolant R32 and R290 heat pump SCOP > 4.47. Kolant use 2 electronic expansion valves. One special EEV is to control the EVI function. It increase the performance at super cold weather condition dramatically.
What is the benefits of Kolant EVl heating technology?
Kolant enhanced vapor injection technology has greatly improved the heating capacity of the compressor in cold environment. The series products can heat stably in the temperature range of -30℃~42℃, and this breakthrough achievement leads the multi-line technology into the era of "strong cold and heat". With Kolant accurate optimization, Kolant EVI heat pump can work well even at -35℃ ambient temp.
Split Design for more anitfreeze
The split heat pump is designed to outdoor unit and indoor hydraulic unit. The indoor installation space is more flexible. The water system is all at indoor unit to improve greatly for the antifreeze function. When indoor unit is installed at good insulated space(Always >0C), no need to use glycol.
Reliable running under environment temperature to -35C air temp Getting much higher water temperature during low environment temperature Heating capacity up to 40% higher than normal heat pumps COP 10%-20% higher during low environment temperature.
Smart WlFl control
By the innovative technologies,Kolant heat pump is able to use Wifi cloud control and enable authorized user to control KOLANT heat pumps anytime, anywhere just via a mobile phone. Just imagine that you turn on your heat pump on your way home, then you can enjoy the comfortable environment created by KOLANT heat pumps as soon as you arrive at home. The Wifi control will also send error code to provide much help on aftersales service.
Modbus Protocol available
In addition to wired controller, Wifi control function, KOLANT heat pumps are specially designed to provide modbus protocol inside,the modbus can control the whole heat pump function and check the parameters. This means your heat pumps can be controlled by your computer or any other automatic control system if it is necessary. This is specially useful for the central control or customized control system.
Reliable and durable
All the important components of KOLANT EVl heat pumps are from world-famous brands to make sure the high reliability and durability within its permitted operating range.
Kolant EVI heat pump Control Advantage and Environmental Protection Performance In terms of control
Kolant EVI enhanced vapor injection heat pump also performed well. Through computer technology, users can easily set parameters and inquire about the state of air conditioning, realize the automatic management of air conditioning and simplify the control process. At the same time, the compressor also has the advantages of health and environmental protection. During the operation of the system, the power frequency does not need to be changed, and only simple mechanical movement is used to load and unload, thus avoiding the possible harm to people and precision instruments caused by high-order harmonics generated by frequency conversion air conditioners.
