Air conditioning is not heating the reason I believe that many non-professionals are not sure Xi'an central air-conditioning agents, then you do not tell your air conditioning and heating What are the reasons, there is no air-conditioning and heating how to do, so you can become a professional: Step : Air conditioning is not heating causes: air conditioning capillary or a problem with the check valve capillary: capillary network simulation veins and capillaries human mechanism, the outer diameter of 3.5-5.0mm (about 0.9mm thickness) capillary and outer 20mm ( wall thickness of 2mm or 2.3mm) of the supply and return tubes trunk pipeline network. Check valve: also known as a check valve or check valve. For the hydraulic system to prevent reverse flow of oil flow, or compressed air for pneumatic system to prevent reverse flow. This causes the air conditioning is not heating how to do: replace the capillary or the check valve can be resolved without air conditioning and heating. Air conditioning as demand varies, different air-conditioning equipment installed what's features: 1, different functions, different devices ① If only the desiccant cooling room air conditioning how to central Xi'an, the choice of low prices some of the cold-type air conditioners device. ② If it is cool all year round, but without excessive moisture place Xi'an Central air-conditioning agents, can be used dehumidifier. 2, split air conditioners, has a smaller interior noise advantages: ① the installation of complex, to be professional and technical; ② due before indoor and outdoor piping line is docked at the scene, it is not uncommon refrigerant leak had to use annual raise situation refrigerant; ③ the price is relatively higher; ④ have to have enough space to install an outdoor unit.
