How to make a prototype
To make a prototype we only need $2000
1 water pump
7 one way valves
2 tanks each 10 litters in size
1 oil separator
1 air-conditioner.. second hand with its compressor not functioning
We need 7 one way valves
BCV check valve, for fluorinated refrigerants
We need one sensor
We need one water pump
PEDROLLO PQ3000 pump with peripheral impeller - 3HP / 2,2KW / 380VStock code = PE_41PQT947A5
PQ 3000 - Pump with peripheral impeller The hydraulic characteristics of this pump, coupled with its compactness, make it suitable for use in the industrial applications. Suitable for use with clean water and liquids that are not chemically aggressive towards the materials from which the pump is made. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather. Pumped liquid: clean water Use: industrial Type: surface Range: peripherals Performance range • Flow rate up to 50 l/min (3 m³/h) • Head up to 180 m Application limits • Manometric suction lift up to 8 m • Liquid temperature between -10 °C and +90 °C • Ambient temperature between -10 °C and +40 °C • Max. working pressure 18 bar • Continuous service S1
Frequency Electric: 50HZ
We need 4 Solenoid Valves
We need 4 Solenoid Valves –Parker Brand - Size :½ " , Part No 444494W
We need 2 steel bottles
We need 1 Oil separator
We need 1 second hand air-conditioner
We remove the compressor we weld all the parts above as shown in the diagram below.
This prototype just to prove the cooling capability of JPS then we can make very nice looking air-conditioners for the market where the two bottles and the pump and every thing so compact it will sit in the compressor place so easily.
this explanation was for the prototype but when making an air-conditioner for market we can put the double headed impeller pump in a casing with its solenoid valves in a metal compartment just like we do now for the compressor, so as if we remove the compressor and we replace it with the double headed impeller pump. then we connect it with the two steel bottles then we have one single unit the pump and the two bottles as one unit to be connected to the rest of the air-conditioner system.
