CDU cold quantity distributes unit: CDU cold quantity distributes unit flow control and thermoregulation program
As industry and commercial architectural increasingly grow in quantity, taller and taller also to the requirement of air conditioning system. CDU (Cold Distribution Unit, cold quantity distributes unit) the crucial component in regarding air conditioning as the system, its flow control and thermoregulation function affect the moving efficiency of whole system and user experience directly. The article discusses development CDU cold quantity to distribute unit flow control and thermoregulation program, aim to provide professional, practical guidance for the reader.
One, CDU cold quantity allocates unit overview
CDU cold quantity distributes unit is air conditioning will cold quantity is in charge of in the system equal apportionment arrives the equipment of each area. It waits for composition by system of evaporator, fan, control normally. The action of CDU is will cold quantity carry each extreme equipment from aircrew of air conditioning of collect Chinese style, wait like group of fan coil, new fan, realize the accurate control of pair of indoor temperature thereby.
2, CDU cold quantity allocates unit flow control
1.The importance of flow control
The flow control that CDU cold quantity distributes unit moves to the stability of air conditioning system crucial. Reasonable flow allocates can ensure each area acquire sufficient cold amount, avoid local super-cooling or overheat appearance, raise the sources of energy to use efficiency.
2.Flow control plan
(1) decide flow control: Through set fixed discharge is worth, make CDU outputs constant flow. This kind of plan applies to not tall to temperature requirement circumstance.
(2) change flow control: Change according to indoor temperature, the discharge of self-correcting CDU. When indoor temperature is worth under set, reduce flow; When set of indoor temperature prep above is worth, increase flow. This kind of plan applies to taller to temperature requirement circumstance.
(3) intelligent flow control: Combine the element such as the indoor temperature, humidity, temperature outdoor, the trends that realizes CDU discharge through intelligent algorithm is adjusted. This kind of plan has taller energy-saving effect and easy measurable.
3, CDU cold quantity allocates unit thermoregulation
1.The importance of thermoregulation
The easy that CDU cold quantity allocates unit thermoregulation function to affect indoor environment directly is measurable. Reasonable thermoregulation can satisfy an user to be opposite the demand of indoor temperature, improve life quality.
2.Thermoregulation plan
(1) only lukewarm control: Through set a fixed temperature is worth, make CDU outputs constant temperature. This kind of plan applies to not tall to temperature requirement circumstance.
(2) double lukewarm control: Two temperature are worth set, CDU is according to indoor temperature change between two temperature value switch. This kind of plan applies to taller to temperature requirement circumstance.
(3) much more lukewarm control: Many temperature are worth set, CDU is according to indoor temperature change between many temperature value switch. This kind of plan applies to extremely tall to temperature requirement circumstance.
4, CDU cold quantity allocates unit applied advantage
1.Energy-saving environmental protection: Through optimizing flow control and thermoregulation plan, CDU can reduce specific power consumption effectively, reduce the effect to the environment.
2.Raise easy measurable: Reasonable flow and thermoregulation, can make indoor environment more easy, raise user satisfaction to spend.
3.The system is stable: The stability of CDU runs the integral stability that can assure air conditioning system, lower fault rate.
4.Safeguard easily: CDU structure is simple, facilitate safeguard and overhaul.
Anyhow, the flow control that CDU cold quantity distributes unit and thermoregulation plan to air conditioning system move crucial. Through be designed reasonably and be being optimized, the efficiency that CDU can develop, provide comfortable, energy-saving indoor environment for the user. In the design of air conditioning system henceforth, the application of CDU will be wider and wider, for our country the energy-saving career that decrease a platoon make contribution.
