In recent years, with the improvement of people's living standards, household central air-conditioning has gradually entered the field of daily home purchase. Purchasing a central air conditioner, eliminating the cumbersome purchase and installation of various rooms in the kitchen living room bedroom, and with reasonable decoration design, can also best meet the needs of the use of the apartment and the aesthetic needs of the interior decoration, currently on the market There are various types of central air conditioners, and what are their advantages and disadvantages? How to choose correctly from the perspective of consumers? In general, the central air conditioners in the existing market are roughly divided into the following points.
1. Water/water heat pump type hot and cold water unit + fan coil system using water as cold heat medium
1 advantage
1. The energy consumption ratio is high, which is 30% higher than the previous type;
2. The temperature of each room can be adjusted freely;
3. The water pipe takes up less space and is easy to decorate.
2 disadvantages
1. The system is complicated, and the cost is higher than the previous one, and the construction quality is not high, there are hidden dangers of water leakage, and maintenance is troublesome;
2, affected by the climate, can not work normally below -5 °C, need to install auxiliary heating device, also need to consume some additional energy. The central air conditioners selected by the National Exhibition Home are single-cooled. In winter, they use urban heat to transmit thermal energy through the summer cooling pipeline.
Second, the air / air heat pump type air conditioning unit that uses air as the cold heat medium
Send cold or hot air to each air-conditioned room through the duct.
1 advantage
1. Solving the problem of indoor fresh air supply and winter air humidification to a certain extent;
2, the system is simple, the cost is the lowest of the three types, and the maintenance is convenient.
2 disadvantages
1. The temperature of each room is not well adjusted separately;
2. The air duct occupies more space, about 100×200 square millimeters, and it needs to reduce its interference to the space through the decoration technique;
3. When the outdoor temperature is less than -5 °C, the outdoor unit has low energy efficiency, low heat production and poor technical safety. Of course, some products are equipped with auxiliary heating devices to ensure that the outdoor unit can still work at -15 ° C or even -20 ° C, but it needs to consume some additional energy. For example, Luther air conditioners in the United States can work normally at -18 ° C.
3. Air-cooled heat pump type air conditioning system directly using Freon as medium
The system is composed in a way similar to the current one-to-two, one-to-three air conditioners, except that the number of indoor units that can be towed can reach more than a dozen or even thirty.
1 advantage
1. The temperature of each room can be adjusted freely;
2. The pipeline takes up little space.
2 disadvantages
1. Subject to climatic conditions, auxiliary heaters must be installed when used below -5 °C;
2. It is difficult to solve the problem of fresh air supply and winter humidification;
3. The cost is relatively high.
Little friends, through the introduction of the coldest bacteria above, everyone has a deeper understanding of the central air conditioning! I hope to help you buy central air conditioning!
