Central air conditioning in several forms - three types of central air conditioning and the advantages and disadvantages of comparison

The development of the central air conditioning, has completely bid farewell to the traditional "aristocratic products" image, become everyone wants to try home functional equipment. Between beauty and comfort, it is not only get rid of the large central air conditioning volume, expensive shortcomings, but also realize the ordinary air conditioning can not be realized 360 degrees of comfortable air effect, so the central air conditioning in recent years has made quite rapid development, quite a replacement for the traditional air conditioning trend. In the actual purchase of central air conditioning process, the central air conditioning in several forms is a topic of concern to most consumers, experts say that at present, the central air conditioning there are three main systems, respectively, refrigerant system, water system, air duct system. There are several forms of central air conditioning - the basic definition of various central air conditioning Refrigerant system:

Outdoor unit through the refrigerant pipe (generally copper) and multiple indoor units connected to the inner unit of each room are refrigerant and air direct heat exchange. (The outdoor unit compresses the refrigerant, and then the refrigerant is transported to the indoor unit through the copper pipe, and the refrigerant exchanges heat with the indoor air at the indoor unit.) Water system:

The outdoor unit is generally called the hot and cold water unit, and the indoor unit is generally called the fan coiler, which is connected through the water pipe. (The outdoor unit compresses the refrigerant, which then goes to heat exchange with water to produce cold/hot water, and the water is sent to each indoor unit with a pump, and the indoor air exchanges heat with the water to achieve the purpose of temperature regulation.) Duct system:

The outdoor unit is connected to one duct-type indoor unit through refrigerant pipe, the duct-type indoor unit treats the indoor air uniformly, and then the treated air is sent to each room through the duct. There are several forms of central air conditioning - advantages and disadvantages of refrigerant system Advantages: 1, comfortable to use, temperature fluctuations are small, especially inverter type is not easy to give birth to air conditioning disease

2, because of the use of inverter compressor, each room can be individually controlled, compared to other units can save about 30%

3, heat transfer efficiency and energy saving is good, only the refrigerant and the air-conditioning heat transfer, more direct

4, no water leakage, all of the water leakage problem, all the air ducts to send treated air to each room, and then the air ducts to send the air to each room.

5, low running noise, easy maintenance of the system, basically no maintenance Disadvantages: higher initial investment - > generally higher than other systems 20% -30% Comfort 100 network expert comment: refrigerant system originated in Japan, Japan's energy basically rely on imports, one of the principles of product development is energy saving, of course, also inseparable from the comfort. Comfort, so the refrigerant system products are energy-saving, comfortable as the basic characteristics. At present, the refrigerant system central air conditioning mainly Japanese brands, Daikin, Mitsubishi Electric, Hitachi, Toshiba, etc. are fluorine system central air conditioning representatives, of which, Daikin is the world's top-selling central air conditioning brand for many years. There are several forms of central air conditioning - water system advantages and disadvantages Advantages: 1, high precision temperature control, constant temperature, no cold and hot phenomenon, good comfort

2, low operating noise, but also a quiet environment

3, easy to coordinate with the interior decoration, with the embodiment of the elegant style

4, the machine running costs are low, even if only one room to use, because of water temperature control switch, long shutdown time, the water temperature control switch, the water temperature control switch, the water temperature control switch, the water temperature control switch, the water temperature control switch, the water temperature control switch, the water temperature control switch, the water temperature control switch, the water temperature control switch, the water temperature control switch, the water temperature control switch. Control switch, long downtime, will not waste electricity Disadvantages: 1, the water system installation, insulation requirements are high, must be operated by a professional team to prevent leakage

2, the selection of water pipe material requirements are high, it is recommended to use PP-R pipe

3, the maintenance of late trouble, more auxiliary components, the system failure rate increases. If you do not maintain in time, the heat transfer efficiency is reduced, the operating costs rise greatly Comfort 100 network expert comment: central air conditioning water system is also known as small air-cooled heat pump chiller, compared with fluorine system and wind system, the biggest advantage of the central air conditioning water system is a good degree of comfort, young and old. At present, the central air conditioning water system is mainly led by the United States brand, Trane, York, Carrier, McWhirr and other brands are internationally renowned, among them, Trane central air conditioning has been known in the industry as the best brand of central air conditioning water system, in addition to refrigeration, it can also be used in conjunction with the gas wall-hung boiler, to achieve the trinity of refrigeration, heating and hot water for domestic use. There are several forms of central air conditioning - duct system advantages and disadvantages Advantages: relative to other small household central air conditioning type, duct system initial investment is smaller; new air system makes the air quality to improve human comfort Disadvantages: 1, an internal machine corresponds to an external machine, the overall noise there is a bias

2, is not like the other central air conditioning is inverter, the operating costs are higher

3, Duct shuttling in various rooms, the requirement of ceiling hidden, sometimes may have to destroy the over-beam. Restricted by the height of the floor, home decoration and ceiling Comfort 100 network expert comment: relative to other types of household central air conditioning, duct system central air conditioning, although the initial investment is small, the introduction of fresh air can effectively improve the quality of indoor air, but but the air duct system air distribution system requires a larger building space, generally require homes to have a high floor height, while it is later running noise, high operating costs, so for the family generally do not recommend this type of system. Families generally do not recommend this type of system. There are several forms of central air conditioning, in summary, the current central air conditioning mainly refrigerant systems and water systems, of course, there may be similar to ground source heat pumps and other air conditioning, but also attributed to the water system air conditioning, which is the most environmentally friendly refrigeration heating system, generally used in villas, although the initial investment is higher, but the later energy-saving effect is significant; refrigerant systems and water systems central air conditioning products with different performances, quotations are also Not the same, you can refer to more central air conditioning prices, users can choose the most appropriate central air conditioning system according to the product brand, performance and the use of their own home needs.
