All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, ... When Daikin launched the VRV* air conditioning system in 1982, it introduced the world's first use of variable refrigerant volume control. Also referred to as a VRF system, variable refrigerant flow is a technology that circulates only the minimum amount of refrigerant needed during a single heating or cooling period. About VRV. When Daikin launched the VRV air conditioning system in 1982, it introduced the world's first use of variable refrigerant flow control. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones.

The VRF or variable refrigerant flow is also known as the VRV system. Both of them are referring to the same thing. Currently, the VRF system has three types; a) air-cooled, b) water-cooled and c) geothermal (not very common). Most of the time, an air-cooled VRF system is used in houses. SCHE refers to VRF systems with characteristics of energy recovery. The ratio of total capacity (heating and cooling) of a system to effective power consumption is defined. The SCHE ratings of Hitachi VRF systems are as high as 32.2. IEER communicates cooling efficiency at different part-load conditions based on weighted operation. VRF systems require much less ceiling space than conventional systems because only the refrigerant piping and ducted outside ventilation air are accommodated. VRF system applications . Heat pump systems are used in restaurants, lobby areas, clubhouses, or religious facilities where there is a defined cooling or heating mode of operation. 3.01 VRF unified heating and cooling (variable refrigerant flow systems) shall have published performance ratings certified by AHRI (Air-Conditioning, Heating, and Refrigeration Institute) and listed in the AHRI Standard 1230 certified product directory. 3.02 All VRF system components shall be manufactured in production facilities maintaining the

The VRF-OAP system refers to a heating, ventilation, and air conditioning (HVAC) system to complement a ventilation function, which is not provided in the VRF system.

Think of VRF as the "Rolls-Royce" of Air Conditioning Systems. It's a very sophisticated technological air conditioning system, based on several principles: Refrigerant only - where refrigerant is the only coolant material in the system (in contrary to the chilled water systems, where refrigerant is used for cooling/heating the water ...
