No heating appliances sense 丨 air conditioning? Save these is worse than the maintenance of the master

As you all know, in the cold winter air conditioning heating effect is not so ideal, so why on earth winter air conditioning system. 。 。

the national meteorological center issued warning cold blue, a cool rain coming, the country all over the country 10 ~ 12 ℃, the temperature drops local fall more than 15 ℃. As you all know, in the cold winter air conditioning heating effect is not so ideal, so why on earth winter heating air conditioning effect is not good, what are the causes? This paper explains the common factors of air conditioning heating effect is not good.

1, what is the main principle of air conditioning heating?

air conditioning heating, gas freon compressor pressurized, become the high temperature and high pressure gas, enter indoor machine of the heat exchanger ( At this time for the condenser) , condensing liquefied exothermic, become a liquid, heat the indoor air at the same time, so as to achieve the purpose of improving indoor temperature. Liquid freon decompression by the throttle device, into the outdoor heat exchanger ( At this time for the evaporator) Gasification, evaporation heat, become gas, at the same time absorb the quantity of heat of outdoor air ( Outdoor air become more cold) 。 Become freon gas entering the compressor start again the next cycle.

2, why the weather is cold, heating effect, the worse?

the weather is cold, the outside temperature is low, air conditioning heating air heat from the outdoor air environment and the difficulty of the increase, lead to the heating effect is relatively poor.

3, heating process, why the indoor machine running a period of time to stop supply, a few minutes automatically open again?

air conditioner in the frost. In the process of frost indoor machine will stop working, and will continue to work after. Heating in the winter, because the outdoor heat exchanger ( The condenser) Of evaporation temperature below freezing, can make the flow through the condenser of the outdoor air condenses on the fin and frost, frost affect heat transfer area of the condenser and air circulation, thus affecting the air conditioning heating effect.

4, how to judge whether an air-conditioning heating normal?

air conditioner refrigeration and heating test standard: 15 - the phone is switched on Twenty minutes later, the outlet from the indoor into 10 - 20 mm in the inspection of the thermometer head was used to measure temperature, cooling into the outlet temperature difference should be not less than 10 ℃, under heating condition ( Heat pump air conditioning) Into the outlet temperature should not be less than 15 ℃, electric auxiliary type hot air conditioning into the outlet temperature should not be less than 23 ℃;

5, the outlet temperature of high and low, why can't represent air conditioning has a problem?

normal air conditioning and measurement standards is mainly judged by air conditioning during heating, machine in inlet and outlet temperature difference to decide, as long as the temperature difference to reach standard, which can determine air conditioning no problem. Outlet temperature has a lot of factors, one is the matching problem of machine and the environment, the second is the room temperature, and other external effects, etc.

6, why air conditioning has been turned on, after reaching a certain temperature, the temperature rise is slow?

the room temperature is low, so the air conditioning heating on room temperature ascension is obvious. As room temperature, indoor temperature and outdoor temperature difference increasing, the indoor to outdoor heat transfer will, the more so indoor temperature rise will be slow. When the temperature reached a certain degree, the heat generated by the air conditioner is just are passed to neutralise outdoor, so in this way, the temperature will not to rise again.

in 7, why air conditioning heating, often can hear the noise from the blue marble?

within the air conditioning machine appearance is mostly made of plastic, when the heating ( Refrigeration is also) Small deformation, can have heat bilges cold shrink, plastic shell will generate sound, belongs to the normal situation, such as plastic parts to finalize the design after the situation will gradually disappear.

8, why sometimes air conditioning boot is faulty?

( 1) Newly renovated room within the taste of inhaled air conditioner;

( 2) The other peculiar smell inside the room source within the inhaled air conditioner;

( 3) New machine short-term plastic taste a little, will soon disappear;

( 4) Air conditioner air filters for a long time not to clean.

9 why is indoor machine is not running water, heating, outdoor water?

heating and cooling the contrary, the performance of the work and the house swap. Contrary is indoor machine cooling water, heating, outdoor environment temperature is too cold and the frost attached to the fin, to a certain need frost melt flow down.

why indoor machine 10, sometimes the wind big and small?

a situation in which ac filter is dirty, the wind is uneven, and when a situation is air conditioning heating, in order to ensure that air conditioning blows hot air, indoor motor according to the quantity of heat to automatically adjust the wind speed, a high wind for a while and low wind for a while, belongs to the normal situation.

11, why, when heating indoor machine occasional 'using' the sound of water?

Hangzhou E cool refrigeration Co.,Ltd's has been able to achieve excellent performance in an extremely competitive industry.
