Air conditioning is an essential temperature control household appliances in the modern room. It has the functions of refrigeration and heating at the same time. Relative to the electric fan and electric heater, it is more multi-functional. However, according to different ways, the types of air conditioning systems can also be differentiated. If you understand the relevant knowledge, it will play a certain reference role when you buy air conditioning. Let’s take a look.
The types of air conditioning systems can be divided into:
Centralized (central) air conditioning: Air handling equipment is concentrated in the central air conditioning room, and the treated air is sent to the air conditioning system of each room through the air duct. Suitable for large area, room concentration, each room heat and humidity load is close to the place selection, such as hotels, office buildings, ships, factories, etc. The maintenance and management of the system is convenient, and the noise reduction and vibration isolation of the equipment are easy to solve.
Semi-centralized air conditioning: An air conditioning system with both central air conditioning and terminal units for handling air. This kind of system is more complex and can achieve higher adjustment precision. It is suitable for workshop and laboratory with high requirement of air precision.
Local air conditioning: Each room has its own equipment to handle air conditioning. Air conditioner can be installed directly in the room or in the adjacent room, on the spot air treatment. Suitable for small area, scattered rooms, heat and humidity load difference of the occasion, such as office, computer room, home, etc. The equipment can be a single independent air conditioning phase group, such as window type, split air conditioner, etc. It can also be a fan coil type air conditioner system composed of pipes for hot and cold water, and each room adjusts the temperature of the room as required.
The type of air conditioning system can be divided into:
All-air system: This system is an air-conditioned room of the cooling and heating load by all the treated air to bear. A centralized air-conditioning system is an all-air system.
All water system: This system is the air conditioning room cold and hot load all rely on water as cold and hot medium to bear. It can not solve the ventilation problems of the room, generally not used alone. Fan coils without fresh air belong to this all-water system.
Air-water system: This system is the air conditioning room of the heat and cooling load on both air and water to bear. Fan coil plus fresh air system is such a system.
Refrigerant system: The cooling and heating load of the air conditioning room in this system is directly borne by the refrigerant of the refrigeration system. Local air conditioning system belongs to this type.
The types of household central air conditioning systems can be divided into:
Multi-link system: multi-link system is often said to be a drag, is the main system of Japanese brand central air conditioning. Household central air conditioning multi-link system is based on compressed refrigerant as the transport medium, using a compressor to drive a number of indoor units, outdoor host is composed of external heat exchanger, compressor and other accessories. The indoor unit consists of a direct evaporative heat exchanger and a fan.
Air cooled piping system: Air cooled piping system is mainly composed of outdoor unit, indoor unit and indoor piping system. The characteristics of the system are that the condenser of outdoor unit adopts air cooling, and each compressor and indoor unit are configured one to one to form an independent system. The connecting pipe between the condenser of outdoor unit and the evaporator of indoor unit is refrigerant pipe. The concealed ceiling type indoor unit can be connected to the air duct and the air supply outlet can be evenly arranged in the room according to the indoor space situation, and it can also be connected to the fresh air duct to introduce fresh air.
In fact, the so-called air conditioning system refers to the method of handling indoor air temperature, humidity, cleanliness and airflow speed system. If you have a certain understanding of the air conditioning system, then in your process of buying air conditioning will also play a small role in helping oh.
