A PERFORMANCE OPTIMISING DEVICE FOR AIRCONDITIONING AND REFRIGERATION SYSTEM

Abstract

A performance optimizing device for air-conditioning & refrigeration system comprising of a closed round pipe provided with inlet and outlet holes on both ends which are connected internally with a copper pipe which has fins soldered on it for better heat transfer this device is connected between the suction pipe of the air-conditioning & refrigeration appliance and the evaporator by soldering the both ends into the main air-conditioning / refrigeration system and another small diameter tube is connected from the outer shell of the said round pipe to the inlet of the evaporator of the appliances so that the volume of refrigerant in the main circuit would increase or excess would leave the main circuit back to the round pipe depending on the load condition.

FORM 2 THE PATENT ACT, 1970 (30 OF 1970) COMPLETE SPECIFICATION [See Section 10] TITLE OF INVENTION: A PERFORMANCE OPTIMISING DEVICE FOR AIRCONDITIONING AND REFRIGERATION SYSTEM Applicant: Mr. Geev Keki Panthaki 34B, Shreenagar Society, Road H, Akota, Baroda 390 020 Gujarat. India, The following specification ( particularly ) describes the nature of the invention and the manner in which it is to be performed : 17 OCT 2004 ^7^ " '^ X o Lj THE DEVICE TITLED ' A PERFORMANCE OPTIMIZING DEVICE FOR AIR CONDITIONING AND REFRIGERATION SYSTEM '■ CONSIST OF FOLLOWING : It is made from a round pipe made of copper / iron / brass of diameter ranging from 1.5 inch to 12 inches and has the length ranges from 9 inches to 30 inches as per the cooling capacity of the appliance both the ends of this tube are closed with cover and soldered and has an inlet hole on one end and outlet hole on the other end through this inlet and outlet hole passes the suction pipe of the cooling appliances on this suction pipe inside the round tube there are fins soldered to create better heat transfer between the refrigerant and this suction pipe is also soldered on the inlet hole and outlet hole another small hole of quarter inch diameter is made on the outer shell of the round tube and a pipe is soldered on (his outer shell of the round tube and this pipe is extended and gets connected to the inlet of the evaporator of the appliances. DRAW BACK OF EXISTING APPROACH : Any Refrigeration appliances or air conditioner are designed to give its maximum performance at standard rating conditions. 35 deg C DB ( Dry bulb ) AND 24 deg C WB (Wet Bulb ) Ambient Temperature. If the appliance is operated at other conditions than at rated conditions - using capillary tube it cannot control the refrigerant flow volume, it either becomes a state of excessive or insufficient refrigerant volume and the phenomena such as (1 ) decrease of cooling performance ( 2 ) increase in operating current and (3) excessive loading operations of compressor occurs. ADVANTAGE OF USING INVENTED DEVICE - A PERFORMANCE OPTIMIZING DEVICE FOR AIRCONDITIONING AND REFRIGERATION SYSTEM ' By installing A performance optimizing device for air conditioning and refrigeration system " in the appliances it adds further refrigerant or takes back excess refrigerant from the system depending on the load or super heat degree of me suction gas thereby enabling (1) to exhibit full performance (2) to protect the compressor (3) to give low electricity bills. Existing Refrigeration and air conditioning appliances like Refrigerators, deep freezers, bottle coolers, water coolers, display cabinets, chilled water / soft drinks dispensers, ice cube makers, softy ice-cream makers, air conditioners - window type, split type, package type, ducted type when operated beyond the standard rated conditions under performs and the resultant effect of which shows in higher wattage consumptions, decrease in cooling capacity and overloading of compressor. 2 By installing this device in the refrigeration / air-conditioning system of the above mentioned appliances the performance is increased , the electricity is saved and the compressor is not over loaded. AT HIGH LOAD CONDITION: REFRIGERANT GAS IS EST SUPER HEATED STATE GOES IN FROM THE SUCTION PIPING INTO THE COMPRESSOR THROUGH THE PERFORMANCE OPTIMIZING DEVICE . THIS INCREASES THE PRESSURE INSIDE THE PERFORMANCE OPTIMIZING DEVICE AS THE GAS IS IN SUPER HEATED STATE THE PRESSURE INSIDE THE PERFORMANCE OPTIMIZING DEVICE GOES HIGHER THEN THE OPERATING PRESSURE UNDER STANDARD RATED CONDITION AND THIS HIGHER PRESSURE ADDS FURTHER REFRIGERANT INTO THE MAIN REFRIGERANT CIRCUIT. THIS WAY SUITABLE REFRIGERANT AMOUNT IS ADDED INTO THE MAIN CIRCUIT THROUGH THE CONNECTING TUBE THERE BY ALLOWING THE APPLIANCE TO PERFORM MORE EFFICIENTLY UNDER HIGHER LOADS. AT LOW LOAD CONDITIONS: REFRIGERANT WITH SUPER HEAT DEGREE OF 0 DEGREE ( IN LIQUID AND GAS MIXED STATE ) GOES INTO THE COMPRESSOR THROUGH THE PERFORMANCE OPTIMIZING DEVICE BY THE SUCTION TUBE. WITH THIS THE PRESSURE INSIDE THE PERFORMANCE OPTIMIZING DEVICE GOES DOWN LOWER THEN THE OPERATING PRESSURE UNDER STANDARD RATING CONDITION. BECAUSE OF THE LOW PRESSURE INSIDE THE PERFORMANCE OPTIMIZING DEVICE THE EXCESS REFRIGERANT IN THE MAIN CIRCUIT IS RECOVERED BACK THROUGH THE CONNECTING TUBE. THIS RESULTS INTO PROPER AMOUNT OF REFRIGERANT INTO THE MAIN CIRCUIT THERE BY ALLOWING THE APPLIANCE TO OPERATE WITHOUT EXCESSIVE REFRIGERANT INSIDE THE SYSTEM THEREBY SAFE GUARDING THE COMPRESSOR AND THE LOWERING OF POWER CONSUMPTION. TECHNICAL DETAIL OF ' A PERFORMANCE OPTIMIZING DEVICE FOR AIRCONDITIONING AND REFRIGERATION SYSTEM': This device is made up of a round pipe closed from both ends - the diameter varies with application and the cooling capacity of the appliance and it is installed on the suction line between the compressor and evaporator of the appliance there is another small pipe connected from the side of the round pipe into the entry point of the capillary near the evaporator this round pipe senses the super heat of the suction pipe thereby increasing or decreasing the pressure inside the pipe according to the ambient temperature. If tiie ambient temperature is high the pressure is high inside the round tube and it adds extra refrigerant into the system and If the ambient temp is low the pressure inside the tube is low and it takes back excess refrigerant from the system. Thereby making the appliance work almost to it's full capacity at variable ambient temperature. 3 Enclosed drawing: Figure 1: Shows the Construction Details of ' A PERFORMANCE OPTIMISING DEflCE FOR AIRCONDITIONING AND REFRIGERATION SYSTEM.'
