Description
Technical Field
The utility model relates to an use refrigerant as multi-split air conditioning system who warms up.
Background
At present, the multi-split air conditioner with the floor heating function needs to exchange heat with water, then hot water enters a water pipe of a floor to provide a heat source for a human body, and the multi-split air conditioner needs additional equipment for exchanging heat with water, such as parts of plate exchange, a water pump, an electromagnetic valve, an expansion tank and the like, so that the equipment cost is high and the maintenance cost is also high.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides an use refrigerant as the many online air conditioning system that warms up, effectively solved the problem pointed out in the background art.
The utility model adopts the technical proposal that:
a multi-split air conditioning system using a refrigerant as floor heating comprises an outdoor unit and at least two indoor units, wherein one end of a refrigerant outlet of each indoor unit is connected with one end of a refrigerant inlet of the outdoor unit, one end of the refrigerant inlet of each indoor unit is connected with one end of a refrigerant outlet of the outdoor unit, an electronic expansion valve and an electromagnetic valve are respectively arranged on a liquid pipe of each indoor unit, a gas pipe temperature sensing bulb is arranged at one end of the refrigerant inlet of each indoor unit, and a liquid pipe temperature sensing bulb is arranged at one end of the refrigerant outlet of each indoor unit.
Preferably, the indoor unit is a duct machine and/or a floor heating system.
Preferably, filters are disposed at the front and the rear of the electronic expansion valve.
Preferably, each indoor unit is provided with an independent switch.
The utility model adjusts the opening of the electronic expansion valve through the difference value of the air pipe temperature sensing bulb and the liquid pipe temperature sensing bulb, so that a proper amount of refrigerant circulates in the system, and the superheat degree of the outdoor unit is controlled at the same time, thereby ensuring the reliability of the unit; to a plurality of indoor underfloor heating systems, the trachea temperature sensing average temperature of liquid pipe temperature sensing package average temperature and each underfloor heating system through detecting each indoor underfloor heating system controls every underfloor heating system's refrigerant flow, makes every indoor underfloor heating system refrigerant balanced, the utility model discloses can guarantee that indoor temperature remains the temperature equilibrium throughout, and more be favorable to people to live in, the living environment is also more comfortable, compare in traditional air conditioning system it can provide more even heat radiation and contain the new trend of no blowing sense, this air conditioning system can avoid any noise to disturb user's official working and rest in addition, the interior space is also more wide and quiet, the tuber pipe machine that the room can be used to refrigerate in summer needs simultaneously and supplies air.

Example 1
As shown in fig. 1, a multi-split air conditioning system using a refrigerant as a floor heating system comprises an outdoor unit 1 and at least two indoor units 2, wherein one end of a refrigerant outlet of each indoor unit 2 is connected with one end of a refrigerant inlet of the outdoor unit 1, one end of a refrigerant inlet of each indoor unit 2 is connected with one end of a refrigerant outlet of the outdoor unit 1, an electronic expansion valve 3 and an electromagnetic valve 4 are respectively arranged on a liquid pipe of each indoor unit 2, a gas pipe temperature sensing bulb 5 is arranged at one end of the refrigerant inlet of each indoor unit 2 and used for detecting the temperature of a high-temperature gas of a compressor entering a capillary tube, a liquid pipe temperature sensing bulb 6 is arranged at one end of the refrigerant outlet of each indoor unit 2 and used for detecting the temperature of the liquid pipe after natural convection heat exchange of the capillary floor heating system, the difference between the gas pipe temperature sensing bulb 5 and the liquid pipe temperature sensing bulb 6 is controlled to be 3-7 ℃ for one indoor unit 2, preferably at 5 deg.c.
The indoor unit 2 is an air duct machine and/or a floor heating system.
And filters 7 are arranged at the front and the rear of the electronic expansion valve 3.
Each indoor unit 2 is provided with an independent switch.
When single indoor set 2 is opened, the utility model discloses a theory of operation:
when the difference between the air pipe temperature sensing bulb 5 and the liquid pipe temperature sensing bulb 6 is more than 5 ℃, the opening degree of the electronic expansion valve 3 of the indoor unit 2 is increased, and when the difference between the air pipe temperature sensing bulb 5 and the liquid pipe temperature sensing bulb 6 is less than or equal to 5 ℃, the opening degree of the electronic expansion valve 3 of the indoor unit 2 is decreased.
A plurality of indoor sets 2 are opened, the utility model discloses a theory of operation:
comparing the liquid pipe temperature detected by the liquid pipe temperature sensing bulb 6 of each indoor unit 2 with the average liquid pipe temperature of all the indoor units 2, if the difference is more than 3 ℃, closing the electronic expansion valve 3 of the indoor unit 2, and simultaneously increasing the electronic expansion valve 3 of the other indoor unit 2 with the difference less than 3 ℃ until the difference between the liquid pipe temperature of each indoor unit 2 and the average liquid pipe temperature is controlled to be 1-3 ℃.
Finally, it should be noted that the above-mentioned embodiments are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
