Recently to do some engineering of hvac engineering, they want to install VRV aircon on the first floor, central air conditioning in the second and third floor, I don't understand, these two kinds of air conditioning is not the same? Had heard that VRV aircon is the central air conditioning! The whole central air conditioning is not good?
VRV aircon system is in the electric air conditioning system, refrigerant compressor control through the cycle and enter indoor heat exchanger refrigerant flow, timely meet the requirements of indoor cooling and heat load of high efficiency cooling air conditioning system. Its working principle is: by the control system of collection and indoor thermal comfort parameters, outdoor environment and characterization of state parameters of refrigeration system operation condition, according to the rule of system operation optimization and the rule of the human body comfort, through frequency conversion and other means to adjust the compressor capacity, and control the fan of air conditioning system, electronic expansion valve and so on all control components, guarantee the indoor environment of comfort, stability and make the air conditioning system work in the best working state. VRV aircon system has obvious effect of energy saving, comfortable, the system on the basis of indoor load, continuous operation under different rotational speed, reduce the energy loss caused by frequent compressor start-stop; The compressor frequency startup, reduces the starting current, energy saving, electrical equipment will greatly at the same time to avoid the impact to other electrical equipment and power grids; Can adjust the capacity of characteristics so as to improve the indoor thermal comfort. VRV aircon system design and arrangement of the easy installation, flexible, architectural space is small, easy to use, high reliability, low operating cost, without machine room, no water system, etc. Central air conditioning: suitable for villas, room more units to use, every room need refrigeration, is relatively economic.
VRV aircon system full name is Varied Refrigerant Volume, referred to as "VRV, is a kind of cooling air conditioning system. An outdoor several indoor machine via the line can handle liquid refrigerant. By controlling the amount of refrigerant cycle compressor and enter indoor refrigerant flow rate of each heat exchanger can timely meet indoor cold, heat load requirements. VRV system with energy saving, comfortable, stable running, and many other advantages, and each room can be adjusted independently, and can meet the needs of different room air conditioning load. But the complex system control, material, manufacturing process, the welding of pipes, etc required is very high, and the initial investment is high. A little bit more simple said, family use basic is an outdoor air conditioning connecting an indoor machine, can be called yituo one; VRV aircon system is a connecting many sets of indoor machine, outdoor use among copper pipe connection, is refrigerant flow inside (CFCS), can be called yi tuo, and the house of the same style and the style of the household air conditioning. People often say that the central air conditioning system is water pipe + wind pipe system, building inside the pipe, air duct, tuyere, wall control panel and other facilities, indoor machine mostly fan coil units, room with air conditioning units, water pumps, etc. The above said is simple, want to know more, you can go to the professional web site to see. Hope to help you.
VRV is a kind of central air conditioning, door model for small space, such as, household more
Frequency VRF, central air conditioning circulation medium is water system, is Buddha system and VRV circulation medium, is there a difference!
VRV central air-conditioning outdoor host by of outdoor heat exchanger, compressor and other refrigeration accessories, terminal device is composed of direct evaporative heat exchanger and fan indoor machine. An outdoor several indoor machine via the line can handle liquid refrigerant. 58 air conditioning there are many companies that sell VRV central air-conditioning, such as shandong, rhett, there are still many dealers, daikin, gree, midea have do VRV unit.
