The central air conditioner is an air conditioner that controls a different room to achieve indoor air conditioning by a host through a wind passage or a hot and cold water pipe connected to multiple ends. By adopting the air duct air supply mode, a single host can control a plurality of different rooms and can introduce a fresh air, thereby effectively improving the indoor air quality and preventing the occurrence of air conditioning diseases. The most prominent feature of home central air conditioning is the creation of a comfortable living environment. Secondly, from the aesthetic point of view and the best space utilization, the use of home central air conditioning makes the interior decoration more flexible and easier to achieve various decorative effects, even if you do not like the original Decorating, redecorating, the original central air conditioning system can be changed in harmony with the new decoration.
Therefore, the household central air conditioner is called a one-step, never-ending choice. Household central air conditioner (or household central air conditioner, unit type adjustable central air conditioner) refers to an air conditioner that generates a cold (heat) source from an outdoor unit and then supplies cooling (heat) to each room. It belongs to a (small) commercial air conditioner. One kind. Household central air conditioners are divided into two types: wind system and water system. The wind system is composed of an outdoor unit, an indoor host, a supply air duct, and a tuyere and a regulating valve of each room; the water system is composed of an outdoor unit, a water pipe, a circulating water pump, and ends of each room (fan coil, surface mounted, etc.).
The characteristics of home central air conditioning are:
1. The whole family is in a comfortable condition, avoiding the phenomenon of human body discomfort caused by direct blowing and cold and uneven indoor and outdoor heat caused by other split machines;
2. The decoration is good, and there is no exposed pipeline in conjunction with the decoration;
3. Simple operation, automatic operation, no maintenance;
4. The amount of air supply (heat) can be increased or decreased according to the orientation, function, etc. of each room;
5. Fresh air and humidification can be added to keep the indoor air fresh and hygienic.
The limitations of home central air conditioning are:
1. Arrangement: design and installation should be combined with decoration to achieve good comfort and decorative effect;
2. Power requirements: The electrical load is large. Old-fashioned housing should consider whether the circuit load is sufficient.
Main component classification:
1. The medium used for the indoor heat and humidity load can be divided into:
Full air system
2. Full water system
3. Air-water system
4. Refrigerant system
Second, according to the concentration of air handling equipment can be divided into:
Centralized
2. Semi-centralized
Third, according to the source of the air being treated can be divided into:
Closed
2. Direct current
3. Hybrid (one return air secondary return)
The main components are air conditioning mainframe (cold heat source), wind cabinet, fan coil, etc.
The resin bond Grinding Wheels have excellent characteristics different from the metal-based and ceramic-based grinding wheels. The resin bond grinding wheels have good self-sharpening performance and good elasticity, are hard to plug during processing. The resin bond grinding wheels possess high grinding efficiency and low grinding temperature at the same time. These excellent characteristics make resin bond grinding wheels very good for sapphireand ceramic materials.
