How to choose home air conditioner
Air conditioner purchase: comparison of advantages and disadvantages of various types of air conditioners
1. Single cooling air conditioner
Only refrigeration, suitable for hot summer and warm winter areas, or areas with sufficient heating in winter.
2. Cold and warm air conditioner
It is suitable for hot summer and cold winter areas. When purchasing, we should pay attention to the selection of air conditioning with heating capacity greater than cooling capacity to ensure the heating effect.
① Heat pump type: depending on the special device, the refrigeration cycle of the air conditioner can realize the dual-use of one machine, cooling in summer and heating in winter.
② Electric heating type: a heating device with a group of electric heating wires is added to the single cooling air conditioner to achieve the purpose of heating.
③ Electric auxiliary heating type: air conditioner combining the above two forms. Electric auxiliary heating parts are added in the heat pump body to ensure strong heating in winter. However, it does not seem necessary in places with adequate heating in winter.
The electric auxiliary heating function is generally only used in the high-power cabinet air conditioner.
3. Variable frequency air conditioner
By using high-tech electronic system, the compressor can be effectively controlled according to the ambient temperature (the air conditioner does not stop), which has many advantages such as quick start, stable temperature control, high efficiency and energy saving (more than 30% power saving), ultra quiet, compact and so on. But the price is higher. The price of variable frequency air conditioning is about 50% higher than that of ordinary air conditioning.
4. One for more air conditioning
One outdoor unit with multiple indoor units, connected to the installation space of outdoor units, is also more economical than the installation of multiple split units. However, when working alone, the power consumption is almost 1.6 times that of the one-on-one model, and the noise is large. In addition, if there is a local fault, all machines will stop running.
