The invention respectively controls the flow of the floor heating refrigerant for the materials of different floors and the coefficients and the speed of heat dissipation to the outside, increases the reasonable refrigerant flow for the floor materials with slow heat dissipation, and reduces the refrigerant flow for the floor materials with fast heat dissipation, thereby generally achieving the balance of the temperature of each room and improving the comfort of people.
Description
Technical Field
The invention relates to an EVI waterless floor heating multi-connected control method based on floor material temperature control.
Background
With the improvement of economic level, the purchasing power of consumers is also improved, the consumers are influenced by new crown epidemic situations, the health consciousness of the national people is also improved, the interest of people in creating comfortable families (the characteristics of comfortable families, such as ecology, high efficiency, health and energy conservation) is gradually increased, more and more owners have added comfortable family ranks to make the families more comfortable and provide better life quality for the families.
The energy conservation of the air energy host is undoubted along with the promotion of the northern coal-to-electricity policy, while the EVI waterless floor heating multi-split air-conditioning unit adopts one air energy host in principle, and the air energy host is connected with the tail ends of a plurality of indoor units and a plurality of floor heating capillary tubes, so that when in winter heating, high-temperature refrigerant of the host enters the floor heating capillary tubes to radiate to the floor heating surface to take heat for people, thereby greatly reducing the energy consumption, and the cost is 70% of fuel gas and 80% of a water system; so the utility model is favored by people.
At present, when people decorate and choose floor materials at home, many people's living room choose ceramic tile floor for use, and the bedroom adopts timber apron, but the different external coefficient of heat dissipation of material is different, for example the ceramic tile heat dissipation is very fast, and the timber apron heat dissipation is very slow, will lead to the living room very hot, and the bedroom is not hot, if outdoor host computer increase ability output, the living room can be hotter, if the host computer reduces ability output then the bedroom is hotter not coming, its travelling comfort is just not good yet.
Disclosure of Invention
Aiming at the problems, the invention provides an EVI waterless floor heating multi-connected machine control method based on floor material temperature control, which effectively solves the problems pointed out in the background technology.
The technical scheme adopted by the invention is as follows:
the utility model provides a control method of EVI does not have water floor heating multi-connected machine based on floor material accuse temperature, when opening the floor heating function, every floor heating indoor set adjusts corresponding electronic expansion valve according to its floor material that corresponds:
when the floor material corresponding to the floor heating indoor unit is a ceramic tile, the electronic expansion valve of the floor heating indoor unit is reduced until the difference between the high-pressure saturation temperature of the floor heating module control system and the liquid pipe temperature sensing bulb of the floor heating module is delta T 1 ；
When the floor material corresponding to the floor heating indoor unit is a composite floor material, the electronic expansion valve corresponding to the floor heating indoor unit is increased until the difference value between the high-pressure saturation temperature of the floor heating module control system and the liquid pipe temperature sensing bulb of the floor heating module is delta T 2 ；
When the floor material corresponding to the floor heating indoor unit is compositely ground heated, the electronic expansion valve corresponding to the floor heating indoor unit is increased until the floor heating moduleThe difference value between the high-pressure saturation temperature of the control system and the liquid tube temperature sensing bulb of the floor heating module is delta T 3 Said Δ T 1 >ΔT 2 >ΔT 3 。
Preferably, the Δ T is 1 At a temperature of 8 ℃ and. Delta.T 2 At 6 ℃ and. Delta.T 3 Is 4 ℃.
The invention respectively controls the flow of the floor heating refrigerant for the materials of different floors and the coefficient and the speed of heat dissipation to the outside, increases the reasonable refrigerant flow for the floor materials with slow heat dissipation, and reduces the refrigerant flow for the floor materials with fast heat dissipation, thereby generally achieving the balance of the temperature of each room and improving the comfort of people.
Detailed Description
The present invention is described in further detail below with reference to specific examples.
The invention discloses an EVI waterless floor heating multi-split control method based on floor material temperature control, which is characterized in that before the multi-split control is operated, the multi-split control is preset in a system through an electric control dial according to the floor material corresponding to each floor heating indoor unit, so that the floor material of each room is identified in a multi-connection mode, when the multi-split control is operated, the supercooling degree of an electronic expansion valve can be adjusted through an electric control plate of each floor heating indoor unit, and when a floor heating function is started, each floor heating indoor unit adjusts the corresponding electronic expansion valve according to the corresponding floor material:
when the floor material corresponding to the floor heating indoor unit is a ceramic tile, reducing the electronic expansion valve of the floor heating indoor unit until the difference between the high-pressure saturation temperature of the floor heating module control system and the liquid pipe temperature sensing bulb of the floor heating module is 8 ℃;
when the floor material corresponding to the floor heating indoor unit is a composite floor material, increasing the electronic expansion valve corresponding to the floor heating indoor unit until the difference between the high-pressure saturation temperature of the floor heating module control system and the liquid pipe temperature sensing bulb of the floor heating module is 6 ℃;
when the floor material corresponding to the floor heating indoor unit is a composite floor heating, the electronic expansion valve corresponding to the floor heating indoor unit is increased until the difference between the high-pressure saturation temperature of the floor heating module control system and the liquid pipe temperature sensing bulb of the floor heating module is 4 ℃.
Finally, it should be noted that the above-mentioned list is only a specific embodiment of the present invention. It is apparent that the present invention is not limited to the above embodiment, 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 present invention are to be considered within the scope of the invention.
