Winter is a cold day, and it is believed that air conditioning is available to everyone. Generally speaking, many families are now equipped with regular air conditioning, usually one for a bedroom and one for independence. With the civilianization of central air conditioners prices, more and more households have chosen to install central air conditioners, which can at the same time provide heating and cooling for multiple rooms, and the effect is that central air conditioners will work faster than normal air conditioners, although many households still have doubts about the use of electricity. After all, the heating and cooling of multiple rooms at once is certainly not low in terms of electricity consumption. This post is part of our special coverage of the world health organization (who)。
What's the hac
Domestic central air conditioner (or household central air conditioner, cellable central air conditioner) is an air conditioner that produces cold (hot) sources from an outdoor machine and then supplies cool (hot) to rooms, which is one of the (small) commercial air conditioners. Indoor air conditioning loads are handled centrally by centralized domestic air conditioning and the resulting cold (heat) is transported through a certain medium to the air conditioning room for the purpose of indoor air conditioning。
Distinction between central air conditioning and general air conditioning
1. Decorative perspectives
Central air conditioners: the installation of indoor machines is not space-intensive, with the integration of the central air conditioners and interior fittings, taking full account of the requirements of beauty and comfort。
General air conditioners: common wall or cabinet air conditioners, which in any case occupy space, make it difficult to reconcile the overall decorative style of air conditioners and rooms. Generally, in order to make the air conditioner installation as beautiful as possible, air-conditioning indoor locations will be selected for installation near the outside, but not necessarily very well。
2. Air-conditioning function
Central air conditioning: in addition to the three main functions of general air conditioning, the hac has a new wind system capable of monitoring indoor air quality on a 24-hour basis. Ensuring the health of indoor air while reducing the loss of room heat。
General air conditioners: general air conditioners generally have three basic functions, namely, cooling, heating and dehumidification, which must be replaced by open doors and windows to ensure healthy indoor air quality。
3. Use comfort
Central air-conditioning: the indoor air-conditioning unit of the household is hidden in a local ceiling space, avoiding air-conditioning blowing directly into the human body, making the room more evenly warm and making the room more comfortable。
General air conditioners: regular wall or cabinet air conditioners, the location of interior installations is limited to the installation of outdoor machines, and the location of wind vents and vents is irreconcilable. Refrigeration often results in colder areas to which air conditioners can blow directly, and hotter areas to which non-blowers are exposed, affecting the comfort of living。
4. Purchase of installation costs
Central air-conditioning: central air-conditioning installation is carried out prior to the air-conditioning crane, which is closely related to interior fit-out, with long duration and relatively high cost。
General air conditioners: general wall-mounted, cabinet-mounted air conditioners are relatively affordable, and the installation of general wall-walled air conditioners does not need to be accompanied by renovation, with shorter durations, lower costs or even no cost。
Is there a central air conditioning charge
The more energy efficient the same number of air conditioners, the lower the cost of electricity. Currently, central air conditioners are more energy efficient than usual air conditioners, such as cabinets and splits. That is to say, the energy efficiency ratio for general domestic fractional air conditioners is around 2. 3 ~ 2. 8, while the central air conditioner can reach more than 3. 0 and the rooms can control the temperature independently, with much less electricity consumption than the normal containerized, split air conditioners. In addition, central air conditioners can be used with wall-mounted furnaces and can be used to increase energy efficiency to 5. 0 or more, with the help of ground-based heat pump technologies, so household central air conditioners do not consume much。
Some people must think that one tow of the central air conditioner is so powery that i'm going to need more power than a split air conditioner to drive a bedroom. In fact, since all the out-of-house central air-conditioning units with more than one tow were all frequency transformers, the power was based on the inner machine. For example, you've got a three-and-a-half-piece central air conditioner, you've turned on two indoor machines in the bedroom, and the outside machine is operating at the rate of two, arriving at a set temperature and continuing to adjust power。
A central household air conditioner is equivalent to a few wall-mounted and cabinet-type machines with less electricity than the sum of one air-conditioning unit per room, which works better than a few, operating at a much lower cost than a fractional air conditioner. In the case of two large-size domestic central air conditioners, the air conditioner is open 24 hours in the middle of the summer. The air conditioner works for eight hours at full capacity. The host has a temperature sensor to reach the specified temperature automatic stoppage and saves more than 100 per month。
What is the monthly cost of household central air conditioning
In the case of three rooms, for example, 90 m2 of construction space, all rooms are open, using central air conditioners for three months each year. Empirical working hours of approximately 40 to 50 per cent of the time used are 14 hours per day, with a cooling-house air conditioner of mcc-025 with a cooling volume of 6,800 w and a power of 2,500 w, and electricity consumption of 90 x 14 x 45 per cent x 2500/1000 = 1417. 5 degrees, and 472. 5 degrees per month。
In contrast, when 1. 25 wall-mounted machines are used in each room, with a single cooling capacity of 2,500 w and a power capacity of 1,000 w, the same conditions apply, with three machines in operation, 90 x 14 x 45 per cent x 3000/1000 = 1701 degrees of electricity, which consumes 568 degrees per month。
Based on one dollar per degree of electricity, the cost of domestic central air-conditioning is $472. 5 per month, while the cost of general air-conditioning is $568, compared with approximately $100 per month。
If the size of the room is large and more than three rooms operate air-conditioning at the same time, the smaller the number of rooms where the central air-conditioning is used, and if only one room is opened and the mainframe is not working, the amount of central air-conditioning is also very low, so that the domestic central air-conditioning is not expensive and energy-efficient。
In summary, the hac does not consume electricity, but rather saves it more than normal air conditioning, but the installation of hac is cumbersome and expensive and is unnecessary if air conditioning is not used frequently. This is the central air conditioner cost of electricity, which is introduced to you by the junior editor of the network, and the monthly cost of electricity of the central air conditioner。
