For Daikin Central air conditioner pin We all know the quantity; Another feature of Dakin Central Air Conditioning is its rich products and strong selectivity. Of course, energy saving and comfort are also good. Now let's talk about the advantages and disadvantages of Daikin Air Conditioner.
Features and advantages of Daikin central air conditioner:
Technical Features of Dakin VRV Variable Frequency Household Central Air Conditioning kjjhkVRV is the acronym for Variable Refrigerant Volume. VRV variable frequency central air conditioner - each set consists of an outdoor unit (5HP~48HP) matched with several indoor units (up to 30 units) (0.8HP~10HP) - is a new, more advanced and highly intelligent Freon direct evaporative central air conditioner developed by Daikin Industry Co., Ltd. in Japan.
VRV variable frequency central air conditioner (hereinafter referred to as VRV) combines most of the advantages of household air conditioners and traditional central air conditioners, and also has the following outstanding advantages:
1. Various models of indoor units - there are ten models of indoor units (C, F, K, D, S, M, H, A, L, LM) and 67 different models for the owner to choose flexibly according to needs, which can fully meet the building, ceiling and interior decoration needs of rooms with different purposes.
2. Remarkable energy saving, more than 40% energy saving compared with traditional central air-conditioning——
① VRV adopts fully enclosed spiral frequency conversion compressor It can be adjusted by frequency conversion between 5% and high standard, that is to say, the power consumed by outdoor units is proportional to the number of indoor units turned on. When all indoor units are turned on, the outdoor units consume more power; When only some indoor units are turned on, the outdoor units automatically reduce power consumption by reducing frequency and refrigerant flow; The less the indoor units are turned on, the less power the outdoor units consume.
② The indoor unit and outdoor unit of VRV can match between 50% and 130%, that is to say, under the same conditions, the air conditioner can reach 130% of the cooling (heat) capacity of the traditional air conditioner.
③ One outdoor unit of VRV can carry more than 30 indoor units, which can flexibly optimize the combination of rooms with different purposes, thus greatly saving energy consumption.
④ VRV is Freon direct evaporation type, so the heat exchange efficiency is high.
3. Advanced control to meet the needs of staggered use time of different rooms and convenient management
① The outdoor unit and indoor unit of VRV are equipped with control computer board, which adopts high-precision PI D (proportional integral differential) control, indoor temperature control accuracy is within ± 0.5 ℃.
② The remote controller can be used to realize the wired or wireless independent start stop control of each indoor unit, adjust the temperature, wind speed and direction, and can also be used to realize the hierarchical, zoning or building centralized control of the system.
③ The LCD remote controller also has the function of automatic fault diagnosis and display, which is convenient for daily maintenance.
④ The VRV is stable in operation and easy to control. No special person is required to operate, watch and manage the VRV, saving operation costs.
4. Building intelligent management system B MS Convenient connection of devices - VRV is equipped with advanced interfaces, which can be easily connected with building control computers, or air conditioning control computers with data communication lines or contact signal lines to complete various control and information monitoring functions.
5. Long service life - VRV has a fault free operation time of more than 15 years and a service life of more than 20 years, twice the service life of heat pump units, and 2-3 times the service life of lithium bromide and centrifugal units.
6. Very low requirements for ceiling space height——
① The ceiling space height only needs 360mm, which is particularly suitable for various high buildings with low storey height.
② Because the VRV uses * * * dedicated refrigerant piping, which does not occupy the ceiling space, and the indoor unit is equipped with a condensate lift pump, the installation of the condensate pipe has no slope requirements, so the VRV can generally save 200~300 mm in height compared with the ceiling space required by the fan coil system, allowing people to have a wide activity space.
③ If VRV is considered before soil construction, each floor can reduce the building height by more than 300mm, and the number of building floors can be increased relatively.
7. Purify and beautify the building facade——
① One outdoor unit of VRV can carry more than 30 indoor units, which greatly reduces the number of outdoor units and avoids placing many outdoor units on the facade of the building.
② The length of the refrigerant connecting pipe between the outdoor unit and any indoor unit can reach 100 meters, and the vertical height difference between the two units can reach 50 meters. Therefore, the outdoor units can be uniformly placed on the roof, ground, etc., or they can be arranged in layers or zones according to the owner's requirements, without the need for a machine room.
8. The extreme operating temperature in winter is low, and the heat failure is reduced - VRV has a wide operating range, with a refrigeration operating range of - 5 ～ ＋ 43 ℃ and a heating operating range of - 15 ～ ＋ 15.5 ℃. The heating performance in winter is reliable and the heat loss is reduced. The extreme operating temperature in winter is very low. When the outdoor temperature is - 15 ℃, the VRV still keeps normal heating operation.
9. Very low noise - Daikin * * *'s refrigerator oil level control system ensures the reliability of compressor operation and the stability of refrigerant flow, so that the noise of indoor and outdoor units is very low, and the noise of outdoor units is only 57dB; The noise of indoor unit is generally more than 30 dB, and the lower one is only 29 dB.
10. Effectively avoid leakage of condensate in summer - the indoor unit (C, F, K, A, S, M) is equipped with a condensate lift pump with a lifting height of 250~1000mm, which can also avoid condensate backflow, so as to effectively avoid damaging the interior decoration due to leakage of condensate in summer.
11. Fast and reliable standardized installation - dedicated * * * refrigerant copper pipe and dedicated REFNET connector are used for the refrigerant connecting pipe between outdoor unit and indoor unit, and the installation process is simple and rapid. It can be installed in layers, zones and sections, and delivered in layers and zones.
