1. What are the advantages of Hitachi central air conditioning?
1. The high-efficiency DC variable-speed scroll compressor and continuous frequency conversion technology patented by Hitachi Central Air Conditioning adopt imported Hitachi high-pressure scroll compressor, and the compressor rotor is made of neodymium magnet material, which improves the efficiency. Using continuous frequency conversion technology, the working frequency of the motor can be adjusted freely to realize continuous frequency conversion.
2. Two-stage oil separation is the advantage of Hitachi central air conditioning. The compressor has internal oil separation function. An oil separator is added in the exhaust circuit of the system to realize two-stage oil separation, which makes the system work more efficiently and run more stably and reliably.
3. Hitachi Central Air Conditioning has fast cooling and heating speed, accurate temperature control, DC frequency conversion control technology, which can quickly reach the initial set temperature and can be accurately adjusted according to indoor load. The indoor temperature can be controlled within ±0.5°C of the set temperature.
4. Hitachi central air conditioning has a wide range of operation. In the outdoor environment of -23℃, the outdoor unit can still start heating operation, which can meet the heating demand in winter in the cold area of northern China.
5. The advantages of the super-long refrigerant pipe of Hitachi Central Air Conditioning Co., Ltd. are that the length of the refrigerant pipe between the outdoor unit and the indoor unit can reach 120m (the maximum economic length of the pipe can reach 75m), the maximum total length of the main pipe is 300m, and the maximum vertical height difference between indoor and outdoor units can reach 30m.
6. The advantage of Hitachi Central Air Conditioning is the free traction system. The outdoor unit can tow up to 9 indoor units (for example, 160 type). There are 9 indoor units to choose from, which can meet the individual needs of users more conveniently and freely.
7. The advantage of Hitachi central air conditioning is super energy saving. The outdoor unit adopts DC variable speed compressor, compressor continuous frequency conversion technology, DC fan motor and a new type of "two-in-one" heat exchanger with supercooling circuit, which greatly improves energy efficiency. The COP is as high as 4. 10 (take RAS- 140FSYNQ as an example). The whole series of products have passed the national energy-saving certification, and the energy efficiency standards have reached the national energy-saving level.
2. What are the skills for purchasing central air conditioning?
1, pay attention to the applicability of central air conditioning. The central air conditioning suitable for different rooms is different. You can only choose real central air conditioning according to the actual situation of the house. Specifically: choose the model according to the area and orientation of the house: first consider the area and orientation of the house to see if there are large glass windows to calculate the maximum simultaneous use coefficient of the air conditioner.
2. Pay attention to three indicators of central air conditioning quality. People choose central air conditioning at home mainly to improve the quality of life and the comfort of the family. Therefore, when choosing home central air conditioning, comfort has become a problem that must be considered. Comfort is usually considered from two aspects: temperature adjustment and static sound. The noise during operation should not be too loud.
What are the advantages of Hitachi central air conditioning? And the introduction of central air-conditioning purchase skills, these are the main knowledge that Bian Xiao introduced to you in the above article, and I hope it will be very helpful to you.
