The invention discloses a building heat collection and removal system based on sky radiation and solar heat collection, and belongs to the field of building energy conservation and renewable energy utilization. A double-effect shaping phase change plate with double-effect shaping phase change working media and capillary tubes, a sky radiation cooler and a solar heat collector are arranged, and thecorresponding operation of heat transfer circulating media in the capillary tubes in summer and winter is utilized, so that the temperature regulating process of cooling indoors all the day in summerand heating indoors all the day in winter is effectively realized. The building heat collection and removal system has the advantages of the simple structure, simplicity and convenience in control, less difficulty in maintenance and overhaul and wide application range and has good popularization and application values, and the cooling process all day and night in summer and the heating process all day and night in winter can be realized at the same time, so that the use of cooling equipment in summer and heating equipment in winter is reduced, the indoor temperature environment of a buildingin summer and winter is effectively improved, energy is saved, the energy consumption is reduced, and the effects of energy conservation and environmental friendliness of the building are achieved.

The invention discloses an air conditioner and an air velocity control method for the same. An air diffusion plate for reducing air velocity of outlet air of an indoor unit is arranged at an air outlet of the indoor unit, and an air guide plate is also arranged to regulate the air outlet direction of the indoor unit. The method comprises the following steps of controlling the air conditioner to enter an air sensor-free running mode if no air sensor-free control instruction is received when the air conditioner runs in a cooling mode; acquiring set temperature, and judging indoor environmental temperature according to the set temperature; if the indoor environmental temperature is higher than the set temperature, controlling the air diffusion plate to swing or controlling the air guide plate to move upwards, and controlling rotating speed of an indoor fan to be less than or equal to first preset rotating speed; if the indoor environmental temperature is lower than or equal to the set temperature, controlling the air diffusion plate to be closed, controlling the air guide plate to be opened to a preset air outlet angle, and controlling the rotating speed of the indoor fan to be lower than or equal to second preset rotating speed. According to the air conditioner and the air velocity control method for the same, a comfortable temperature environment can be provided, and in addition, a comfortable indoor air velocity environment can further be provided, so that comfort is improved.
