VRV system consists of outdoor unit, indoor unit and refrigerant pipeline. An outdoor unit is connected to a plurality of indoor units through refrigerant pipes, and the flow and state of refrigerant delivered to the indoor units are controlled according to the signals fed back by the computer boards of the indoor units, so as to meet the requirements of cold and heat output in different spaces.
General structure of common air conditioner: refrigeration system, ventilation system and electrical control system. Compressors, condensers, evaporators, throttling pipes, thermal expansion valves and drying filters in air conditioners all belong to refrigeration systems. Fan, fan motor and ventilation duct constitute the main parts of air conditioning and ventilation system. Compressor circuit, temperature control circuit, protection circuit and other circuits constitute the electrical control system of air conditioner.
2. Different application fields
VRV is a small central air conditioner, which is mostly used in large-sized houses, such as family villas and small commercial spaces.
Ordinary air conditioners are mostly used in houses, offices, etc.
Types of VRV air conditioning system
1, one-to-one: small unit inverter air conditioner: indoor unit has embedded and air duct. Embedded systems are 3HP and 5HP. The models of air ducts are 3HP, 5HP, 10HP and 20HP. Commonly used in various shops, small offices, restaurants and other places.
2. One-trailer-three (four, five) household central air conditioning: there are four types of indoor units: embedded, air duct, floor-mounted and wall-mounted. The maximum outdoor unit is 6HP, and it can be connected with up to 9 air-conditioned indoor units. It is often used in senior residences, duplex apartments, villas, duplex shops and other places.
3. One-to-one commercial central air conditioning: There are four types of indoor units: embedded, piped, floor-mounted and wall-mounted. The maximum outdoor unit is 48HP, and it can be connected to 64 air-conditioned indoor units at most. The longest single pipe is 165m, and the maximum difference between indoor and outdoor is 90m. Often used in office, commercial and residential, catering and other occasions.
4.CMS commercial space frequency conversion multi-connected air conditioning system (commercial and office frequency conversion special air conditioning): the maximum outdoor air conditioning is 18HP, and the maximum indoor air conditioning can be connected to 15 units. The longest single pipe is 120m, and the maximum difference between indoor and outdoor is 50m. Commonly used in 150 ~ 5000m2 office and commercial space.
