Wow you must have some knowledge about refrigeration systems.
as with all freon based systems, they do work on temp absorption. you must also know that a so called "cooling" device doesnt actually cool, but it takes away heat.
this is how they produce a cooling effect and remove heat from the items we want cooled.
like a refrigerator or an air conditioner.
they all use compressors and freon to absorb the heat from the place we dont want it.

if you need more info just reply here.
thanks tzweeb

Trying to get 2008 Jaguar VDP inspected after service done. I've driven 200+ miles and computer still reads not ready. What's next step?


You must complete a OBD2 drive cycle, unless you do the kind of driving that satisfies the computer testing you can drive for a year. Go here for the test and how you need to drive to complete the drive cycle.


1 Ensure that fuel filler cap is fully closed (minimum three clicks).

2 Fuel level > 30% and < 85%.

3 Using WDS scanner perform ECM DTC Clear (even if no DTCs are flagged).

4 Drive vehicle for a minimum of 2 minutes, and until engine is at normal operating temperature.

5 Using WDS, ensure that the EVAP Canister Purge Valve is operating by observing "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE". If the valve is not

active, ECM adaptions have not been learned. Conduct a "green ECM" Drive Cycle as described in Technical Service Bulletin.

6 Drive vehicle to the road where the EVAP System Drive Cycle will be conducted. Stop vehicle and switch OFF the ignition. Leave ignition OFF for 30 seconds,

then restart the engine.

7 Accelerate briskly to 80 km/h (50 mph) ensuring that the engine speed reaches a minimum of 3500 rpm for a minimum of 5 seconds.

8 (0.040 inch EVAP Test) View WDS "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE", "CANISTER CLOSE VALVE - VAPOR RECOVERY SYSTEM", and

FUEL TANK PRESSURE - VAPOR RECOVERY SYSTEM". Avoiding high engine loads, drive the vehicle steadily between 65 km/h (40 mph) and 100 km/h (60

mph). Avoid driving conditions that will produce excessive fuel movement. WDS should give an indication that the test is active (it may take up to 30 minutes

before the test will initialize). When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.

9 (0.020 inch EVAP Test) Continue driving vehicle as explained in Step 8 for an additional 10 minutes.

10 Gently coast the vehicle to a stop. Allow the engine to idle for 2 minutes and view WDS "PURGE VAPOR MANAGEMENT VALVE - DUTY CYCLE", "CANISTER

CLOSE VALVE - VAPOR RECOVERY SYSTEM", and FUEL TANK PRESSURE - VAPOR RECOVERY SYSTEM". WDS should give an indication that the test is

active. When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.

11 If the 0.020 inch EVAP Test is not activated, the purge system vapor concentration may be too great. To reduce the vapor concentration proceed as follows:

12 Drive the vehicle for an additional 30 minutes avoiding driving conditions that will produce excessive fuel movement. Repeat Step 10. If the 0.020 inch EVAP

Test is still not activated, repeat the Drive Cycle from Step 6.
13 Using WDS, check for and clear flagged DTCs

How do I get a operating and trouble shooting manual for a dometic royale rv refrigerator?


Contact the manufacturer, Absorption refrigeration is an infrequently used alternative to compression refrigeration. Absorption refrigerators use a solution of ammonia and water as refrigerant fluid. A gas flame heats the ammonia and provides the energy that drives the cooling process. These models are generally very simple and have few moving parts. This is a very straightforward process. There are three main principles behind proper operation of an absorption refrigerator. Place the refrigerator on a level surface. Make sure that it is adequately ventilated. Check that the correct heat is being applied in the boiler. As long as there are no leaks, this should be enough for the refrigerator to work properly.

Fridge quit cooling. The heating element works and propane works. Gets really hot but fridge does cool. There was no smell of ammonia and no yellow residue. What could it be?


How can "fridge quit cooling" but later you say "but fridge does cool" of course this absorption cycle system gets hot on the outside, heat is the "driver" of the system rather than an electrically driven compressor in the normal fridge. Is this a homework problem?

Unclog personal humidifier doesn't work


If this is an ultrasonic humidifier, in the bottom of the humidifier is a little disk that vibrates to turn water to vapor. This gets covered in mineral deposits and won't vibrate properly. They usually suggest something like vinegar to clean it. I found that this didn't work for me. What did work was cleaning it with my Waterpic on the highest setting. It chipped away the deposits and allowed it to work. HOWEVER, once you get it running again, buy the slant fin mineral absorption pads to keep it running. If you have mineral-rich water like me, you'll go through them quickly, but you also won't have white deposits on your walls anymore.

Freezer pipe broke is ti safe?


The pipe you refer to does not exist. Piping on a domestic refrigerator consists of [1] a liquid refrigerant pipe or [2] a vapor refrigerant pipe. In either case, if you are close to either of them when they "break", they could cause damage to you. After the referigerant charge has finished discharging, they are generally not dangerous.

Is it possible in aircon to used it with no compressor??


Nothing in air conditioning is new. It has been done for many years.

There are three types of "compressorless" refrigeration that I can think of.

1. ) swamp coolers or evaporative coolers - these work on the process of adiabatic saturation in low humidity environments. Evaporating water removes energy from the air, makes it cooler and more humid. This is a win-win when the air is very dry, but the process doesn't work well in humid environments, were water evaporates less readily.

2.) Peltier junction solid state coolers. These are essentially a thermocouple driven in reverse. Conduction between the hot and cold plates is hard to control and at low voltages these devices need a lot of current. These units are not as efficient as mechanical refrigeration.

3.) Absorption refrigeration cycle. In these systems a solution of ammonia in water (or water in a lithium bromide brine) is used. Heating the water (or brine) drives out the ammonia (or water vapor) and takes the place of the compressor in the cycle. This cycle is useful if you have a source of waste heat. You essentially recover the energy in the waste heat to run a refrigeration unit. A few demo units have used solar energy as the heat source, but I don't think this is common
