American Trane central air conditioning introduction

With the continuous development of modern society, the technology of central air conditioning is also constantly developing, its application range is also constantly extending, compared with ordinary air conditioning, central air conditioning will make the room more comfortable, more and more families in the renovation of the choice of central air conditioning, and the Trane Central Air Conditioning as an important brand in the central air conditioning market, loved by the consumers, so the US Trane Central air conditioning what is the working principle? The following is a small introduction for you.

A, the United States Trane central air conditioning working principle

Refrigeration:

1, liquid vaporization refrigeration is the use of liquid vaporization of heat absorption, condensation exothermic effect to achieve refrigeration. Liquid vaporization to form steam. When the liquid (refrigerant) in a closed container, the container in addition to the liquid and the liquid itself produced by the steam, there is no other gas, the liquid and steam will reach equilibrium at a certain pressure, the vapor is called saturated steam, the pressure is known as saturation pressure, the temperature is called the saturation temperature.

2, the equilibrium of the liquid is no longer vaporized, then if a portion of the steam from the container, the liquid must continue to vaporize a portion of the steam to maintain this balance. Liquid vaporization to absorb heat, this heat is called latent heat of vaporization. Latent heat of vaporization comes from the object to be cooled, so that the object to be cooled to become cold. In order for this process to continue, the vapor must be continuously withdrawn from the vessel and condensed into a liquid and then returned to the vessel.

Heating:

1, the compressor inhales low-pressure gas compressed by the compressor into a high-temperature, high-pressure gas, high-temperature gas through the heat exchanger to raise the temperature of the water, and at the same time the high-temperature gas will condense into liquid. Liquid into the evaporator for evaporation, (evaporator evaporation at the same time there should be heat transfer media, according to the heat transfer of different media machine model structure is also different. Commonly used air-cooled and ground source.) Liquid through the evaporator into a low-pressure low-temperature gas, low-temperature gas is again inhaled by the compressor for compression. In this way the cycle continues, the air conditioning side of the circulating water becomes hot water of about 45-55 degrees. Hot water through the pipeline to the room to be heated, the room is installed with a fan coil heat exchange of hot water and air to achieve the purpose of heating.

Second, the advantages and disadvantages

Advantages:

1, high comfort: Trane central air conditioning each indoor unit has an air supply and a return air outlet, the air circulation is more reasonable, the indoor temperature is more uniform, you can maintain a constant temperature of ± 1 ℃, the human body feels more natural and comfortable, especially the water system central air conditioning, comfort is very high; and the traditional household wall-hung machines and cabinet units, prone to airflow. Machine and cabinet, prone to airflow dead zone, the indoor temperature difference is obvious, easy to get air conditioning disease.

2, the use of low-cost: the traditional split unit by the indoor ambient temperature changes in the larger, fixed-frequency air-conditioning compressor starts and stops frequently, high power consumption, and Trane central air-conditioning using DC inverter technology and the new refrigerant technology, each indoor unit can be individually controlled, which need to be cooled in the room on the opening of the room, the outdoor unit "on-demand output The outdoor unit "output on demand", so that the compressor has been in the best working condition, power consumption is small, and, the larger the room area, the more cost-effective installation of central air conditioning.

3, long life: the service life of household split air conditioning (wall-mounted and cabinet) between 5-8 years, while the service life of the central air-conditioning for home use between 15-20 years, of which, Trane central air-conditioning water system service life of 25 years, if it is a ground-source heat pump central air-conditioning system, the system service life of 50 years. So, the service life of a Trane central air conditioner is at least double that of a home unit.

Disadvantages:

1, the installation of complex: Trane central air conditioning installation is a complex technical project, on the one hand, the need to synchronize with the renovation, on the other hand, the installation requirements are very strict, under normal circumstances, the air conditioning factory is only half of a semi-finished product, the air conditioning must be installed in the end-users, debugging is completed, an air conditioner can be considered a qualified finished product!

2

2, occupying a large area: Trane central air conditioning generally need a large indoor area, it needs to be placed in the room to occupy a certain area, with the window and split air conditioning installed on the wall and window compared to the use of it is not suitable for use in small rooms.

3, power consumption: Trane central air conditioning power are relatively large, generally more than 2 horses, so the power consumption is very high, the work of the circuit requirements are relatively high, if the cross-section of small wires and small meters are not able to meet the needs of the best to use copper-core wires and more than 20A meter, in order to avoid possible pitfalls.

The above is a small introduction to the Trane central air conditioning principle of operation and advantages and disadvantages of the introduction, through the above introduction, we know that although Trane air conditioning has certain disadvantages, but Trane air conditioning is still good, Trane central air conditioning cost-effective, quality, after-sales service in the central air conditioning market is relatively excellent.
