Description
Technical field
The invention belongs to air-conditioning equipment fields, more particularly to a kind of double interior hanging machine air conditioner systems.
Background technique
In the decentralized heating area in south, the most important mode of warming is using air conditioning and heating.With fuel heating with
Electric heating system compares, this kind of mode can enter room from the more thermal energy of outdoor carrying on the basis of consuming unit of electrical energy
It is interior.
However, since air-conditioning is installed in the indoor position close to ceiling.The position for causing warm wind to be sent out is higher, even if
Larger air supply velocity is set, is generally also only capable of blowing to the position on head.Simultaneously as hot-air is lighter, sent out from air outlet
While begin to move to ceiling, cause to form convection current in region between ceiling in portion in a room,
And to smaller by the region effect between floor in the middle part of room locating for people.It results in as a result, and blows warming by air conditioner often
It is that face heat is felt cold.
In addition, the air inlet due to traditional air conditioner is arranged on air outlet, it is more nearly the position of ceiling, leads to it
What is sucked is the air close to indoor maximum temperature.This will lead to of both consequence: on the one hand, the setting of general temperature controller into
At air port, height where the temperature considerably beyond indoor people that the hot-air close to ceiling position of sucking shows air-conditioning
Observed temperature causes room temperature to be unable to reach preset temperature.On the other hand, since the hot-air of sucking wants on-hook sent to the room
Inside carries out heat exchange, its temperature spread between high temperature heat source is caused to reduce, and reduces heat exchanger effectiveness.Meanwhile so that into
The temperature of the working medium of row throttling expansion is higher, increases the temperature difference between low-temperature heat source (outdoor air), causes from Low Temperature Thermal
Source heat absorption energy consumption increases.That is, increasing the power consumption of air-conditioning.
It is therefore proposed that a kind of air-conditioning system for being more suitable for warming is very important.
