Sanyo Compressor C-SB453H8F due to many factors, inverter air conditioner more and more accepted by the majority of users. The use of variable speed compressor, increasing the system's adjustable parameters to improve the performance of the air conditioner part load, with flexible control variable capacity instead of the start-stop control, reduce the impact of fluctuations in indoor temperature of the system and on the grid, from energy efficiency and comfort point of view than the fixed speed air conditioner has obvious advantages. Home central air conditioning with quite different, specific differences in heat load requirements, conditions of use, which calls for residential central air conditioners and heat energy regulation can be a wide range of load change to adapt to this characteristic, most of the sales on the market energy regulation air source units are only achieved by opening the compressor stops when the air-conditioning heat load is small, the air conditioning system capacity is small, prone to frequent compressor open to stop, because the starting current of the compressor is large, thus making the operating power consumption increase; and each time after shutdown cooling system high and low side pressure after some time to reach equilibrium, balancing the high-pressure side heat when mixed refrigerant and the low pressure side of the cold refrigerant will cause unnecessary cold the amount of loss. In addition, the opening stop too often will shorten the life of the compressor. In recent years, with advances in air conditioning technology, the home central air conditioning products in a variety of energy has emerged adjust the way, way more applications are: ① refrigeration system using a plurality of fixed speed (fixed volume of gas) compressor combination; ② Cooling system with variable amount of gas compressor and constant speed compressor combination; ④ combination of a plurality of refrigeration systems; ③ refrigeration system using inverter compressor and constant speed compressor combination. For a combination of a plurality of cooling system units, energy regulation system with the number of different types of compressor has a large difference, the use of fixed speed (fixed volume of gas) compressor system combination can only achieve energy distribution regulation, such as using variable speed compressor system with a combination of fixed speed compressor system is able to achieve continuous energy regulation. Therefore, as a modular product structure, design-related specifications and fixed speed units-conversion unit, through a variety of combinations, can also be formed continuously adjustable energy products. Sanyo Compressor C-SB453H8F wide range of application requirements, cooling (heating) quickly, the system water temperature fluctuation is small, the water temperature during the defrosting small decline, but also has significant energy savings can be achieved continuous energy regulation large capacity unit, and the increase unit life and improve comfort and reduce noise are good room, home central air conditioning is worth developing a strong proponent of the way. 4. Thermal stability of the water system when Sanyo Compressor C-SB453H8F home air source units and single-unit compressor cooling is constant speed compressor, since the smaller water capacity air conditioning system, there will be thermal stability of air conditioning water system. Equipped with air-source household air-conditioning system fixed speed compressors, energy regulation generally according to room temperature changes is achieved by opening the compressor stops. Most home air conditioning systems are running at partial load, partial load, the compressor is running very short time, the air conditioning system water temperature will reach the set temperature, then the compressor stops; when the small water system capacity, after a very short time air conditioning system water temperature will be higher than the set temperature, the compressor and must be switched on, resulting in frequent compressor open to stop, not only increasing the power consumption, but also affect the life of the host. Further, when a small water system capacity, will cause the temperature drop during the winter defrost system is too large, the impact the heating effect, the phenomenon of the formation of cold blow. Inverter compressor and constant speed compressor combination of the air conditioning system, the host can automatically match with the indoor load, thermal stability of the water system is not outstanding, but the water system capacity is too small, the inverter compressor and constant speed compressor convergence Load blind will cause the compressor start and stop times. The smaller water capacity of the system, the worse the thermal stability of the system, whereas the thermal stability of the system as possible. However, if the system water content is too large, it would cause huge storage tank volume cycle, when start-up and long-term impact for the first time after shutdown cooling (heating) rate. Accordingly, the water system design, should proofread computing system water capacity meets the requirements of system thermal stability. When the system water capacity can not meet the requirements, it should be added to the tank storage cycle or take measures to increase the diameter of the pipe system. 5. Indoor and outdoor layout and design Sanyo Compressor C-SB453H8F home central air-conditioning methods and equipment selection OK, when air conditioning indoor unit arranged fully take into account the temperature distribution, air distribution, maintenance issues, safety and other aspects, and the building should fit properly. Relationship places (indoor, outdoor, balcony, etc.) provided air-conditioning equipment and building construction (position, equipment reservation channels, etc.) and household room layout (windows, furniture and location) should be clearly indicated on the design drawings come out. National and local laws and regulations should also be strictly enforced in the air-conditioning equipment layout and design. You must consider the installation location and noise control design of the outdoor unit. Usually the unit into the wind for a smooth installation location, speed control in 3 ~ 4m / s, the exhaust is not blocked, especially above the outlet should not have barrier may cause a short circuit exhaust gas flow, the crew due to thermal protection action and stop. 6. Water piping system designed home central air-conditioning systems are generally smaller, simpler design of water system design issues that need attention are as follows: (1) water system circulating manner Sanyo Compressor C-SB453H8F water systems generally use two closed-loop control system comfort requirements are particularly high in the upscale residential four-pipe can be used. Due to the small scale system, water pipeline use different programs.
