Air -conditioning system multi -connected system training device

The --r -conditioning system of a variable refrigerant flow system (VRV, VariaBlereFrigerantvolume) is a power -conditioning system in the power and --r conditioning system. Traffic, in real time meet the high -efficiency cold -conditioning --r -conditioning system required by the indoor hot and cold load. The VRV --r -conditioning system has many advantages such as energy saving, comfort, smooth operation, and small occupied building space. It can better meet the user's personalized requirements, and is widely used in buildings of hundreds to 20,000 square meters.

2. M--n features

1. The system adopts VRV unit, which is characterized by excellent quality, small volume, and frequency conversion regulatory adjustment. The regulating range of the frequency conversion compressor is between 48%and 104%of its rated capacity. Its energy adjustment must take into account the time required for the frequency adjustment of the compressor. Due to the dynamic characteristics of the frequency conversion compressor itself, it should be less than that of the energy adjustment energy than the energy. A cert--n speed, so the adjustment is step -by -step and regulate in stages; the speed of the compressed motor motor is transformed according to the indoor --r conditioner load.

2. The diversification of system terminal processing machines: allow students to understand the diversified structural form of the indoor unit. Each terminal processor is equipped with a refrigeration system process board, control circuit flow board, thermometer, and pressure gauge, which can be observed that the entire control circuit of the unit can be observed.

3. The integrity and independence of the system: It is completely consistent with the control function, protection function, and display function of the actual home central --r conditioner. Each user terminal can be controlled independently under the same working conditions.

The operating table can be put into use for 220V power supply, covering a small area, saving houses and reducing infrastructure investment.

4. The device visually shows the system structure and working principle of the home central --r -conditioning, which is convenient for teachers 'demonstration explanations and students' understanding of textbook knowledge. The structure is reasonable, the shape of the beautiful shape is reasonable and compact, and the shape is beautiful and generous. The tr--ning table also has four universal wheels and four fixed regulatory agencies to facilitate movement and fixation.
