1, electric auxiliary heating
To some extent, the problem of low room temperature and slow heating process in winter is solved by electric auxiliary heating, and the installation position of electric auxiliary heating in central air conditioning is also very important. Midea TR series household central air conditioners installed with electric auxiliary heat hiding are safer than grid FG series central air conditioners installed with electric auxiliary heat at the air outlet.
2. Safety
Judging from the size of indoor unit and outdoor unit, Midea KFR-51T2W/BP2DN1-TR and Gree FGR5Pd/Ena central air-conditioning indoor unit feel as light and thin, while Midea TR series indoor unit has a smaller depth and saves more indoor space. Midea KFR-51T2W/BP2DN1-TR has higher safety performance.
3. Refrigeration effect
Midea TR series household central air conditioner adopts a new generation of dual-rotor DC inverter compressor, and the refrigeration capacity reaches 5. 1kW. Gree FG series central air conditioning adopts high-efficiency compressor, and the refrigeration capacity reaches 5kW.
In the same area of space, two beautiful TR series household central air conditioners can reduce the indoor temperature to the set 24℃ within 14 minutes; The same two Gree FG series central air conditioners also reduced the indoor temperature to the preset 24℃ within 15 minutes.
In terms of cooling capacity and time, Midea KFR-51T2W/BP2DN1-TR has greater cooling capacity and faster cooling time than Gree FGR5Pd/Ena central air conditioner. Both air conditioners can reach the preset temperature range within 15 minutes, and the cooling effect is remarkable.
Extended data:
Central air conditioning is usually closed and stopped in winter and will be put into operation in summer. It has been out of service for nearly half a year, and a comprehensive inspection is needed before turning on important air conditioners. The maintenance and cleaning of the central air conditioner must be arranged before it is turned on in summer. The shell, fuselage and filter screen of outdoor unit and indoor unit need to be carefully inspected and cleaned, and then start trial operation to observe the speed and effect of air cooling.
The maintenance frequency of central air-conditioning should be determined according to the operating hours of air-conditioning, environment, climate, cleanliness of environmental dust, sanitary conditions of rooms and many other factors. Generally speaking, it is enough to maintain 1-2 times during the probation period from startup to shutdown.
In addition, in the use of central air conditioning, scientific use can not only prolong the service life of central air conditioning, but also effectively save energy and electricity. It is necessary to adjust the reasonable air outlet direction and set the appropriate temperature. Remember not to block the air outlet of the air conditioner, which will not only reduce the cooling effect of the air conditioner, but also consume a lot of electricity, and try to avoid switching the air conditioner on and off frequently.
