Abstract

This invention is characterized by an air conditioning system that jets actively a refrigerant into an evaporator in an active jetting manner so as to enhance the diffusibility and uniformity thereof.

Claims

1. A temperature regulation system with an actively-controlled injection-type refrigerant supply and regulation, comprising:

a condenser (CON100);

an evaporator (EVA100) having at least one surface on an interior or exterior of the evaporator (EVA100) from which refrigerant in a small particle or fine mist state is evaporated to carry thermal energy away from the surface;

a fine particle or mist forming refrigerant injection device (IJ100) for accelerating and transforming a liquid state refrigerant (REF100) supplied by the condenser (CON100) into the small particle or fine mist state and injecting the transformed refrigerant onto the at least one surface of the evaporator (EVA100);

a pipe (P100) for circulating a refrigerant (REF100) between the condenser (CON100) and the evaporator (EVA100) via the refrigerant injection device (IJ100);

a pressure reduction throttle device (R100) connected between the condenser (CON100) and the injection device (IJ100) and comprising one of an expansion valve, a capillary device, and a liquid level control device for reducing a pressure and throttling of said refrigerant (REF100) supplied in a liquid state from the condenser (CON100) to the injection device (IJ100);

an operation input device (OID100) for inputting operation signals to control actuation or stopping of the system, select operation modes, regulate temperature settings, and set an air output level when a fan is installed;

a drive circuit device (CD100) connected to the refrigerant injection device (IJ100) for controlling an amount and intensity of the refrigerant (REF100) injected into the evaporator (EVA100) in a fixed or periodic scan driving direction, said refrigerant (REF100) being sprayed into the evaporator as one of a refrigerant stream, fine particles, or mist; and

an electric control unit (ECU100) connected to receive the operation signals from the operation input device (OID100) and for supplying control signals to the driving circuit device (CD100) to control a pressurization and injection timing of the refrigerant injection device (IJ100) in order to control said injection amount and intensity.

2. A temperature regulation system as claimed in claim 1, wherein the refrigerant injection device (IJ100) is one of a mechanical, electromagnetic, magnetostrictive, and piezoelectric injector.

3. A temperature regulation system as claimed in claim 1, further comprising a fluid compression pump (PUMP100) connected to an outlet of the evaporator (EVA100), said outlet enabling escape of a vaporized or incompletely vaporized said refrigerant (REF100), for compressing the vaporized said refrigerant (REF100) and supplying vaporized and compressed said refrigerant (REF100) to the condenser (CON100).

4. A temperature regulation system as claimed in claim 1, further comprising a temperature detector (TD100) for detecting a temperature of the evaporator, wherein said electronic control unit (ECU100) controls said driving circuit device (CD100) in response to temperature detection signals from the temperature detector (TD100).
