1. How about Hitachi central air conditioning?

Advantages of Hitachi Household Central Air Conditioning: Energy Saving and Environmental Protection

The set-free system adopts R407C/R4 10A environmental protection refrigerant, which is efficient and energy-saving, will not destroy the ozone layer and is harmless to human body.

Advantages of Hitachi household central air conditioning: 95-stage variable speed compressor

The compressor speed of Hitachi central air conditioner changed from 20Hz to 1 15Hz 1Hz and * * 95. Combined with adaptive control technology, the capacity output can be automatically adjusted according to the actual air conditioning load to ensure a smoother change curve to meet the higher requirements for comfort, while other air conditioners generally have frequency conversion of 13, 24 or 35.

Advantages of Hitachi household central air conditioning: Hitachi fully enclosed DC variable speed scroll compressor

The world's first scroll compressor for air conditioning was manufactured by Hitachi in 1983. The outdoor unit of the sleeve-free system adopts the DC variable speed scroll compressor patented by Hitachi, and adopts neodymium magnetic materials and optimized rotor shape design, which integrates the manufacturing experience of Hitachi 2 1 year scroll compressor. The characteristics of scroll compressor, such as small leakage, high efficiency, low noise, small vibration and long service life, have been fully reflected in the outdoor unit of disassembly-free mini-system.

Advantages of Hitachi Household Central Air Conditioning: Dedicated High Efficiency Heat Exchanger

1. Use 2? Where to? 1 heat exchange process increases the wet cycle of refrigerant heat exchange and greatly enhances the heat exchange effect.

2. Free of setting? The fins of the outdoor and indoor heat exchangers of the system are made of high-quality accordion hydrophilic aluminum foil imported from Japan, which improves the heat exchange efficiency by 30% (compared with the previous slit sheet), and is corrosion-resistant, wear-resistant and oxidation-resistant;

3. Adopt the patented tooth-shaped high-efficiency internal thread heat exchange copper tube developed by Hitachi Metal Company, which Hitachi calls the thermal optimal tube to optimize the heat exchange; Using this tube can reduce the amount of refrigerant while ensuring cooling and heating.

Advantage 5 of Hitachi household central air conditioning: PFC control technology and PAM control technology are adopted.

1. Due to the electronic interference filter and automatic protection device, when the power supply voltage suddenly rises or falls, the compressor and inverter will not have a chain reaction due to system failure, which greatly reduces the failure rate; In addition, due to the silencer, the noise is completely reduced.

2. The frequency conversion drive of compressor adopts PAM control technology. By increasing the voltage to speed up the operation frequency of the compressor, the output of the compressor is greatly increased, and the indoor temperature quickly reaches the set temperature. The space vector control technology is used to adjust the compressor speed, the refrigeration capacity and the indoor temperature accurately.

3. Using PFC control technology, the power factor of Hitachi household air conditioning system is improved and the energy-saving effect is increased.

Second, is Hitachi central air conditioning good?

Technical advantages of Hitachi central air conditioning;

1.？ Hitachi central air conditioning compressor, inverter and other major spare parts are all imported.

2.？ Silent technology climax, reaching the lowest 2 1 dB in the industry. (Street 70 decibels, quiet library 30-40 decibels)

3.？ Small size, beautiful appearance and space saving, the thinnest is only 19.2㎝.

4.？ Temperature control is close to precision air conditioning. The trinity temperature controller adopts inlet, return and remote temperature controller, and the temperature is controlled at about 0.5℃.

5.？ Variable frequency compressor (stepless frequency conversion between 0- 100%, Daikin, Toshiba, mitsubishi electric, etc. There are graded frequency conversion. )

6.？ Scroll compressor (Hitachi introduced scroll compressor as early as 1983, so it can be said that Hitachi is the originator of scroll compressor. )

7.？ Intelligent defrosting, defrosting time 1/3 (precise defrosting control makes defrosting more accurate, only 560 seconds. )

8.？ Strong heating effect (using large-capacity scroll compressor is the most advanced compressor in air conditioning industry at present, which makes the working range of the unit wide by 40-23℃)

9.？ The secondary oil separation technology makes the refrigerant separation more pure, with stronger carrying capacity and relatively energy-saving. 13.？ The inclination angle can be adjusted by about 0.25 horse according to different people.

Brand achievements of Hitachi Central Air Conditioning;

1.？ Invented the world's first air-conditioning scroll compressor.

2.？ Hitachi ranks first in sales in Japan.

3.？ The second generation frequency conversion technology is more energy-saving than Toshiba's first generation frequency conversion technology.

4.？ 10P, 12P main engine with side air outlet is more flexible to install.

5.？ The thickness of the internal machine is only 19.2 cm, which makes the installation more flexible.

6.？ COP value is the highest in the industry, and IPLV value is the highest in the industry.
