Problems solved by technology

When an ordinary air conditioner is in cooling mode, see Figure 1-Figure 2, as the outdoor temperature rises, the cooling effect will decrease. When the outdoor temperature rises to a certain level, the condensing pressure reaches or exceeds the design value, and the air conditioner The control system of the refrigerator will enter the protection mode to protect the refrigeration system from high temperature and high pressure damage; when the outdoor temperature is low and the cooling capacity is low, or when the indoor temperature is close to the user's set temperature, the required cooling capacity Ordinary air conditioners can only switch on / off frequently, which brings large temperature fluctuations to the user's environment, and frequent on / off switching also wastes more power
[0003] When the ordinary air conditioner is in the heating mode, as the outdoor temperature drops, the heating effect will decrease. When the outdoor temperature drops to about -10 degrees, the heating effect of the ordinary air conditioner will seriously deteriorate and cannot meet the needs.
When the outdoor temperature is relatively high, the output heating capacity is more than needed. Ordinary air conditioners can only be switched on / off frequently, which also brings large temperature fluctuations to the user's environment, and frequent on / off switching is also waste more power

Abstract

A delivered power adjustable air conditioner includes evaporator, condenser, and throttle component, and spray-steam type compressor and flash evaporation are arranged in air conditioner. And first throttle component and second throttle component, first four-way valve and solenoid valve are arranged in the air conditioner, and outlets of the evaporator are respectively connected to low pressure inlet of the spray-steam type compressor and C port of the first four-way valve, and the inlets of the evaporator are connected to the second throttle component and the flash evaporation in sequence, and the inlet of the condenser is connected to the high pressure outlet of the spray-steam type compressor, and the outlets of the condenser are connected to the first throttle component and the flash evaporation in sequence, wherein, D ports of the first four-way valve are connected to the solenoid valve and the high pressure inlet of the spray-steam type compressor in sequence, and the flash evaporation is connected to E port of the first four-way valve. A second four-way valve is arranged in the air conditioner. The invention has been greatly improved, and can adjust delivered power.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner with adjustable output power. Background technique [0002] The air conditioner is divided into three parts: the indoor unit (indoor unit), the outdoor unit (outdoor unit), and the connecting pipe assembly connecting the indoor and outdoor units. The heat exchanger of the indoor unit is generally called the evaporator, and the heat exchanger of the outdoor unit is generally called the condenser. The main components of the outdoor unit refrigeration system of the cooling-only air conditioner include a compressor, a condenser, a throttling mechanism (such as a capillary tube) and piping components. The main components of the outdoor refrigeration system of heat pump air conditioners include compressors, condensers, throttling mechanisms (such as capillary tubes), electromagnetic four-way valves, and piping components. The current non-inverter and non-variable air condition...
