Abstract

The utility model relates to a seasonal air distribution switching control device for a central air conditioner. The seasonal air distribution switching control device comprises an air treatment unit which is respectively connected with a first air pipe and a second air pipe in series. The first air pipe is connected with a top air port, and the second air pipe is connected with a lower air port. The first air pipe and the second air pipe control air flow direction through an air supply and return switching device. During cooling of the air conditioner in summer, the top air port of a room is an air supply port, the lower air port of the room is an air return port, air distribution of the room with the air conditioner is in a manner of 'supplying on the top and returning from the bottom' and both the temperature and the humidity of the room are suitable for the requirement for comfortableness of people. During heating of the air conditioner in winter, the top air port of the room is the air return port and the lower air port of the room is the air supply port by the aid of the air supply and return device, hot air is supplied from the lower portion of the room, and the air distribution of the room is in a manner of 'supplying from the bottom and returning from the top', so that the temperature and the humidity are suitable for the requirement for comfortableness of people, waste of energy resources due to the fact that hot air cannot flow downwards in winter is avoided, and heat utilization rate can be increased to great extent.

Description

The central air-conditioning air current composition switching control that changes according to the season

Technical field

The utility model relates to the switching control that changes according to the season of a kind of central air-conditioning air current composition summer in winter, can realize " summer air current composition send next time on being, winter air current composition for serving back down " the central air-conditioning air current composition switching controls technology of changing according to the season.

Background technology

Along with the raising day by day of living standard, people also improve the requirement of comfortableness day by day.As everyone knows, cold air is to sinking, and hot-air is to come-up, and human body requires too environmental amenity, and when the head temperature is minimum, when the downward temperature of health raise gradually, the comfortableness of human body was best.Thereby draw the air conditioning mode of the most comfortable: summer, cold air sent from top to bottom, and winter, hot-air sent from the bottom up, had just in time met air flow direction and human comfort requirement.

For public building large space particularly; Usually adopt the all-air conditioning system, promptly after the air process air-treatment unit cooling, be dispensed to each air-conditioned room through air outlet through air supply duct; Make the humiture of air-conditioned room reach designing requirement; Air is collected to the air-treatment unit through return air inlet and return air duct again and handles once more, so constantly circulation, and the humiture of air-conditioned room is able to maintain lastingly design point.The air current composition of all-air system, adopt at present on more the having serve back, on send next time, side send and pushes up back etc., no matter which kind of form of employing, annual airflow direction all can not change, summer in winter airflow direction is the same.Since summer cold air sink with winter the hot-air come-up in the opposite direction, the winter air-conditioning effect is undesirable when guaranteeing the summer air-conditioning effect, if guarantee the winter air-conditioning effect, the air-conditioning effect in summer is undesirable again.

Summary of the invention

In order to solve summer in winter room conditioning air current composition is required different problems, the utility model provides a kind of central air-conditioning air current composition switching control that changes according to the season.

The utility model device scheme is: a kind of central air-conditioning air current composition switching control that changes according to the season; Comprise the air-treatment unit; Be serially connected with first airduct and second airduct on the air-treatment unit respectively; First airduct is connected with the air port, top, and second airduct is connected with the air port, bottom, and first airduct and second airduct come control air to flow to through the air blow and return switching device shifter.

The advantage of the utility model is: during the summer air-conditioning refrigeration; Use as air outlet in the air port that is positioned at the top, room; Use as return air inlet in the air port that is positioned at the bottom, room, and the air current composition of air-conditioned room is " on send next time ", and the direction of sinking with cold air is consistent; The humiture in room met human comfort most and required (human comfort require for increasingly high to the downward temperature of foot from head) this moment, and the air-conditioning effect is best.And when air-conditioning heats in the winter time, change through the air blow and return switching device shifter give, the direction of return air, make the air port at top, room as return air inlet; Use as air outlet in the air port of bottom, room; Hot-air is seen off through the bottom, room, gets back to the air-treatment unit through the top, room again, and winter, the air current composition in room was " serving back down "; Consistent with the direction of hot-air come-up; The humiture in room reaches equally and meets most the human comfort requirement, avoids the winter hot-air can't descend at the top, room, and the air-conditioning effect is best.

Description of drawings:

Below in conjunction with accompanying drawing and case study on implementation the utility model is described further.

Fig. 1 is the operation condition in summer sketch map of the utility model;

Fig. 2 is the winter operation operating mode sketch map of the utility model.

Among the figure: 1, air-treatment unit; 2, first airduct; 3, second airduct; 4, air port, top; 5, air port, bottom; 6, air blow and return switching device shifter.

The specific embodiment:

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Like accompanying drawing 1 and a kind of central air-conditioning air current composition shown in the accompanying drawing 2 switching control that changes according to the season; Comprise air-treatment unit 1; Be serially connected with first airduct 2 and second airduct 3 on the air-treatment unit 1 respectively; First airduct 2 is connected with air port, top 4, and second airduct 3 is connected with air port, bottom 5, and first airduct 2 and second airduct 3 come control air to flow to through air blow and return switching device shifter 6.

Fig. 1 is a central air-conditioning air-flow operating condition sketch map in summer, makes first airduct 2 be ajutage through air blow and return switching device shifter 6, and second airduct 3 is a backwind tube, and this moment, air port, top, room 4 was an air outlet, and air port, bottom, room 5 is a return air inlet.The cold air of handling well through air-treatment unit 1 summer is sent into the room through first airduct 2 with air port, top, room 4, make Temperature and Relative Humidity of Indoor Air reach designing requirement after, be pooled to air-treatment unit 1 through the air port, bottom, room 5 and second airduct 3 again; The air current composition in summer air-conditioning room is " on send next time ", and air current composition is consistent with the direction that cold air sinks, and the humiture distribution in room meets the human comfort requirement most, and the air-conditioning effect is best.
