Air conditioner with constant air outlet temperature and control method therefor

Abstract

This invention discloses an air conditioner and its control method, wherein the air-out of the conditioner has a constant temperature, this air conditioner includes heat pump heat-production unit, heater heat-production unit and master control unit which can check the running parameter of the air conditioner, the master control unit eclectically connects with the heat pump heat-production unit and the heater heat-production unit, which adjusts the output power of the heater heat-production unit and change the indoor fan rotate speed by checking the required heat-production quantity of the air conditioner and the heat pump heat-production to make the sum of heat quantity equal with the designed required quantity of the air conditioner. This invention adjusts the heat-production quantity of the heater automatically according to the change of parameters such as environmental temperature to set the air-out temperature constantly at the best state. When the environmental temperature is lower or the heat-production quantity of the heat pump heat-production is smaller, the heat-production quantity of the heat-production of the automatic adjust electric heater reaches the most point to achieve fast heat-production; on the contrary the quantity reaches the least point to achieve the aim of energy conservation.

Description

technical field [0001] The invention belongs to the field of air conditioners, and relates to an air conditioner with constant air outlet temperature, in particular to the adjustment and control method of the heating capacity of the air conditioner. Background technique [0002] The air conditioners currently on the market simply implement cooling and heating functions. For example, when cooling, when the ambient temperature is higher than the set temperature, the compressor is started for cooling, and when the ambient temperature is lower than the set temperature, the compressor stops running; When heating, when the ambient temperature is lower than the set temperature, start the compressor for heating (if there is an electric heater, start the electric heater for heating), and when the ambient temperature is higher than the set temperature, the compressor will stop running (if there is an electric heater then stop the heater). In fact, when the air conditioner works in th...

AI Technical Summary

Problems solved by technology

This kind of air conditioner can only realize simple adjustment of heating capacity, and cannot accurately control the heating capacity of the electric heater with the change of ambient temperature, so it cannot accurately control the temperature of the air outlet of the air conditioner, but the phenomenon of blowing cold air to the air conditioner has been improved.
