With the promotion and popularity of "low-carbon" and "environmentally friendly" lifestyles, "energy saving and emission reduction" has increasingly become an important criterion when people buy home appliances. As the most power-consuming household appliances in the home, the energy saving of air conditioners is not only related to the total electricity consumption of the family this summer, but also affects the living environment around us. Many families want to choose central air conditioners for aesthetics and convenience when decorating, but they are worried that central air conditioners will become the "electric tiger" in the family and do not save energy. So, does the central air conditioner really consume too much power? How can we quickly judge the energy-saving performance of the central air conditioner? Here is a simple and direct way to teach you a simple and direct method, which is to look at the energy efficiency ratio label.
What is energy efficiency ratio?Generally speaking, the energy efficiency ratio (Energy Efficiency Ratio) EER = rated cooling capacity / rated power (power consumption).
I believe that when buying electrical appliances, everyone will notice a blue and white background colored label with the "China Energy Efficiency Label" written on it. This label is a direct manifestation of the energy efficiency ratio of the air conditioner. You can see that there are 1 to 5 grade marks on it, from green to red, and on the left there is a message prompting from "low energy consumption" to "high energy consumption", and the upper right corner clearly shows the energy efficiency grade of the product of this specification.
Energy efficiency label⒉6～2.8 level five (red-high energy consumption)
⒉8～3.0 level four
⒊0～3.2 Level 3
⒊2～3.4 Level 2
â’Š4 and above (green-low energy consumption)
Level 1 indicates that the product has reached the international advanced level, with the most energy-saving, that is, the lowest energy consumption; Level 2 indicates that it is relatively energy-saving; Level 3 indicates that the energy efficiency of the product is the average level of the Chinese market. At present, only level 3 and above are allowed to be sold on the market in our country, and levels 4 and 5 have been eliminated.
Knowing the horsepower and energy efficiency ratio of the air conditioner can calculate the power consumption of the air conditioner. Take the fixed-frequency air conditioner as an example. The first-level energy-efficiency fixed-frequency air conditioner uses only 0.83 degrees of electricity per hour to reach 3000W of cooling capacity, while the 3-level energy-efficient fixed-frequency air conditioner needs nearly 1 degree of electricity per hour to achieve the same cooling capacity.
The energy efficiency ratio of central air conditioners is often higher than that of split air conditionersMany consumers think that split air conditioners are more economical and energy-efficient. In fact, there is a misunderstanding. In terms of energy efficiency ratio, the energy efficiency ratio of central air conditioners is often higher and more energy-efficient than split air conditioners. The energy efficiency ratio of general household split air conditioners is around 2.3~3.6, while the central air conditioner can reach above 6.0, which far exceeds the level of ordinary air conditioners such as cabinet type and split type. Simply put, when the cooling capacity is the same, the use of central air conditioners is more energy-efficient than split air conditioners. Take Hitachi's central air conditioner as an example. Its IPLV (ie, the comprehensive energy efficiency ratio of a single chiller under standard operating conditions under partial load operation) is as high as 6.35, which shows its energy-saving effect.
In fact, the purpose of buying air conditioners is to be able to enjoy a comfortable life. They can be turned on as long as there is demand, so it is better to spend more money to buy products with higher energy efficiency ratio. Of course, if the area of ​​the home is still large, I suggest you consider installing central air-conditioning, because the overall calculation of central air-conditioning is still cheaper than installing a split air-conditioning in each room.
A manual pulse generator (MPG) is a device normally associated with computer numerically controlled machinery or other devices involved in positioning. It usually consists of a rotating knob that generates electrical pulses that are sent to an equipment controller. The controller will then move the piece of equipment a predetermined distance for each pulse.
The CNC handheld controller MPG Pendant with x1, x10, x100 selectable. It is equipped with our popular machined MPG unit, 4,5,6 axis and scale selector, emergency stop and reset button.
