Q: analyze the balance valve in the application of air conditioning and heating system a: the effectiveness of the key facilities mainly shown in the following aspects: 1. Successful implementation of cold and hot water system of water dynamic equilibrium of key parts. The hydrodynamic disorders are random and dynamic changes. Balancing Industrial Valves performance category: probably in the air conditioning and heating system, as to the distribution + 羭 wisp of water circulation system of water dynamic equilibrium is very matter. A hydrodynamic equilibrium system is the basis of satisfied users need, save energy consumption. The system, each user in a preset condition, actual flow with the preset flow not appropriate. Static balancing valve is no way to solve the disorder phenomenon, can only be used to solve the dynamic balancing valve. Namely in the system, when a user's flow of water changes ( Closed or adjust) , actuating system resistance distribute different, thus causes the flow of other users with the changes. Balancing valve application in air conditioning system: variable flow system is in the end facilities department ( Such as fan coil, combined air conditioning box, air treatment machine, etc. ) Adding electric control valves, regulating by indoor temperature stem electric valve opening, to independently regulate the flow of a coil, thus to ensure indoor temperature within the allowed flap. 3. Balancing valve is air conditioning heating is one of the toll for the number of necessary shut facilities. In contrast, in heating season, 1 ~ 2 room will be too hot, 3 ~ 4 layers of the house just reached the preset temperature, comfortable and easy and comfortable 5 ~ 6 layer of the room is too cold. For constant flow system, the disorder can use static balancing valve or valve to solve dynamic equilibrium, the difference is that the former needs instrument regulation, and don't have to. System changes in the flow through the pump set on the inverter speed to achieve success. After installation of dynamic flow balance valve, whether a ~ six-story house still use only part of the house in the use of air conditioning, whole room all can reach the preset temperature. 2. Lateral distribution loop equilibrium system; Guarantee all things whatever load conditions stem valve and terminal device can meet the actual requirements of the preset flow. At the same time, we must pay attention to the change of valve opening, not can support the traffic changes in accordance with the requirements of distribution, so must have the corresponding stem facilities, ability to make the system run more effective. In the air conditioning and heating system, cold ( Hot) Media distribution to each user by closed pipeline system. Called dynamic disorder, also called as safe sex disorders. For a preset good pipe network system, each user at the end of the stem valve ( Electric control valve, temperature control valve, etc. ) Opening of 100 shall be preset can be obtained when one hundred percent water, and at the end of each user stem valve opening change can obtain the needed flow and mutual interference. 3. Balanced stem loop; Security stem valve under the condition of satisfying the office running. Hydrodynamic disorders common is divided into two kinds of static imbalance and dynamic disorder. In the air conditioning cooling season, 1 ~ 2 room will be too cold, 3 ~ 4 layers of the house just reached the preset temperature, comfortable and easy and comfortable room 5 ~ 6 layer is too hot. The static disorder, also called as steady-state misadjustment. 。 2. Thousands of project operation also confirmed that the balance valve is the effect of air conditioning, heating system, increase energy efficiency, reducing energy consumption, loss of construction cost Marine valve guarantee safe and reliable operation, using the door to meet one of necessary shut facilities in the system. The hydrodynamic disorders is the root that being, if not solved, beginning and end of the impact. So the waters of the series is a hydrodynamic equilibrium system, otherwise it is hydrodynamic unjust balance system, hydrodynamic unfair balance is called hydrodynamic disorders. 1. Equilibrium system of cold source side loop; Through the chiller water flow for the fixed value. In a variable flow operation of the system, stem facilities mainly solve the three problems. For example: a building of six storeys, such as the dynamic flow balance valve not installed, the water system in the actual operation of dynamic imbalance.
