Where is the expansion valve on my 1994 Toyota Camry?
Answer to the location of the expansion . The expansion valve is located inside the evaporator core housing on the evaporator core. If you see the large and small pipes coming through the firewall on the passenger side of the engine compartment and trace them into the plastic box behind the glove box, you will find the evaporator core inside this box and the expansion valve is the little aluminum block that is in between those pipes and the evaporator core. It should have a little quarter- like bell on the rear of it. Hope this helps and is in time.

What effects of moisture does Pinus radiatia have?
Monterey pine [Pinus radiata] is native to California. So it handles a humid temperate climate. And it even handles ocean fog that moves inland, and moistens the treetop ka the canopy. But it also handles drier, hotter situations and soils. For example, it has closed cones that release seeds in higher extremes of temperature and higher levels of heat. Because of this adaptability, it can end up on an area's invasive list for crowding out other plants.
What is the effect of moisture content?
In case of pharmaceutical product moisture content play important role.. - During process - During Evaluation - During Stability studies - During process-Formulator has to optimise the moisture content of a materials and intermediates during entire process.If the initial moisture content of excipients and intermediate product(Lubricated granules) vary batch to batch may causes problems.Eg if high moisture contet can lead to tablet sticking,granules poor flow etc. while low moisture content can lead to tablet capping,tablet rougness,granules brittleness. -During Evaluation-High content of moisture in product may cause to low assay content while vice versa.Impurities issue,tablet physical appaearnce etc. -During Stability studies-May cause product degradation mainly,hardness reduction,dissolution differences etc. Thanks Saleem Shaikh

What is ac expansion valve?
An ac expansion valve is the part in the ac cycle where the refridgerant goes from a smaller tube to a wider tube. Traveling through this valve causes the refridgerant to get cold similar to cracking the valve on a air tank. When the gasses go from a high pressure to a lower pressure they get cold ( PV = nrT ). The cold refridgerant then goes through an exchager where the blower blows air across to get the cold air you feel when you turn your ac system on.

How does a thermal expansion valve work?
If you are talking about a temperature and pressure valve on a water heater (pop off valve). It is controlled by spring pressure and a rubber seal. As pressure in the tank increases the tension exerted by the spring on the rubber seal is over come until the point at which excess pressure is released around the rubber seal. When the pressure inside the tank decreases the spring again pushes the rubber seal closed. Temperature of the water in the tank is directly related to the pressure.. higher temperature = more pressure.

Function of expansion valve?
Metering device The metering device controls the flow of liquid refrigerant through the system. The liquid enters at a high-pressure, high-temperature, sub-cooled state and leaves as a low-pressure, low temperature, expanded liquid state. Accurator Piston and Thermostatic Expansion Valves are the most widely used metering devices. Accurator Pistons are widely used because of their low cost and flexibility. The piston can easily be changed to match the capacity of the condensing unit. The Thermostatic Expansion Valve (TXV) is the most efficient type of metering device. The TXV automatically adjusts the flow of the liquid refrigerant based on the superheat of the refrigerant leaving the evaporator coil. As the load on the evaporator increases, the TXV increases the flow of refrigerant. This maintains the proper superheat. The TXV is efficient throughout a variety of system operating conditions, while the accurator is efficient only under designed conditions.
What is thermostatic effects?
The thermostatic effects of water are the properties that act to moderate changes in temperature, which in turn affect Earth's climate. For example, the huge amount of heat energy exchanged in the evaporation-condensation cycle helps make life possible on Earth. The sun radiates energy to Earth, where some is stored in the oceans. Evaporation removes this heat energy from the oceans and carries it high into the atmosphere. In the cooler upper atmosphere, water vapor condenses into clouds, which are the basis of precipitation, such as rain and snow, that releases heat of condensation. The exchange of latent heat between oceans and atmosphere is very efficient. For every gram of water that condenses in cooler latitudes, the amount of heat released to warm these regions equals the amount of heat removed from the tropical ocean when that gram of water was evaporated initially. The end result is that the thermal properties of water have prevented wide variations in Earth's temperature, thus moderating Earth's climate. Because rapid change is the enemy of all life, our planets moderated climate is one of the main reasons life exists on Earth.
Why is The thermostatic expansion valve is freezing up on your air conditioning unit?
The valve it's self may grow some ice on it sine it is common for TXVs to keep the suction pressure a little lower then a fixed orfice system would. When that pressure falls below 32 degrees at a saturated temperature then ice will start to grow on the first couple inches of the evap coil but should melt away on off cycle.
What is the expansion valve?
it is the part in an ac systems that restrics the flow of freon, making it get cold. always just before the evaporator Its more of a nozzle that converts the freon into gas. When freon is in its gas state it gets very cold. In a liquid form, it can get very hot. The temperature varies in different gases. (i.e. R22, R134.etc)

Why is there Moisture in the valve cover?
When the engine starts it is cold, as it warms up it builds heat which causes condensation to form. Since heat rises so does the condensation as it tries to excape through the PVC in the valve cover. As the engine cools it has the same effect, the valve covers are thin metal or aluminum they cool quickly but the oil in the pan is hot which causes the condensation to form on the valve covers.
Will the Evaporator Pressor Regulating valve close if the Thermostatic Expansion Valve is in the evaporator air stream?
The EPR valve should work reguardless of if the TXV is in the air stream. The TXV in the airflow shouldn't make it act any different since it is sensing the temperature at the bulb instead of at the valve it's self.

How does a thermostat make use of a thermal expansion?
Thermal expansion occurs when change in temperature causes change in object such as metal, which expands when temperature rises. Different metals have different expansion characteristics. A metal will change precisely with change in temperature. The rest is easy: apply techniques to switch circuits (furnace/AC) on and off with physical shape change of metal, calibrate switching to correspond to required temperature and measured temperature. This type of control is largely antiquated in thermostat control and replaced with PN junction linear change in base speading resistance used to control sophisticated energy saving equipment. Expansion still used heavily in refrigeration control and heating protection and control.
