Vertical type air conditioner and control method thereof

Abstract

The invention discloses a vertical type air conditioner. The vertical type air conditioner comprises a base and air conditioner bodies arranged on the base, wherein each air conditioner body comprises a housing and a drainage air flue formed in the housing; housings of the adjacent air conditioner bodies are arranged in a spaced mode; an air inlet and an air outlet are formed in each housing; a cross-flow fan and a heat exchanger are arranged in each housing; each air inlet, each heat exchanger, each cross-flow fan and each air outlet are sequentially arranged in the corresponding drainage air flue in the air flowing direction; a penetrating air flue is formed between the housings of the adjacent air conditioner bodies; induced air in the drainage air flues and air in the penetrating air flue are mixed in the penetrating air flue and are fed to a specified area of an air conditioner room; heat exchangers in the adjacent two air conditioner bodies communicate with each other at a concentration point; the concentration point is positioned on the first plane on which the longitudinal middle axis of the penetrating air flue is located; the first plane extends in the penetrating air flue in the air flow flowing direction; an electronic expansion valve is further arranged between the heat exchangers and the concentration point; and a coil tube temperature sensor is arranged on each heat exchanger. The invention further provides a control method for the vertical type air conditioner. The vertical type air conditioner has the advantages of being good in air-conditioning effect and flexible to use.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to a vertical air conditioner and a control method for the vertical air conditioner. Background technique [0002] In order to overcome the problems of complex air supply channels in the prior art when the vertical air conditioner is in operation, causing a lot of noise and attenuation of air volume, a Chinese patent application (application number 201410073610.4) discloses an air conditioner, which is installed on an independent housing An air duct structure with one air inlet and two air outlets. And a cross-flow fan is arranged in each air duct structure to form a wind tunnel leading the wind along the front and rear directions of the shell, driving the air to flow from the back to the front. [0003] The most prominent advantage of this double cross-flow vertical air conditioner is that when the air conditioner is working in the cooling or heating state, the ...

AI Technical Summary

Problems solved by technology

[0004] The double cross-flow air conditioner disclosed in the prior art has the following disadvantages: firstly, the user cannot independently control the wind speed of the double cross-flow fan according to the actual experience; secondly, even if two sets of independent circuits are set to control the operation of the fan, the two heat exchange The refrigerant flow in the heat exchanger cannot be independently adjusted accordingly, and it is easy to cause shutdown or alarm when the air conditioner exceeds the load; moreover, since the confluence point of the heat exchanger is set on one side of the heat exchanger, long-term use will make the two The refrigerant flow allocated by the heat exchanger forms a cumulative deviation and the cumulative deviation gradually increases. If it is necessary to adjust the cooling capacity in the heat exchanger with the fan speed according to the user's demand, it is very easy to overshoot the response, and the probability of alarm and shutdown will be high. Greatly improved, seriously affecting the actual experience of users
