Abstract: An air conditioning system has a refrigeration system that supplies a refrigerant to an evaporator coil enclosed in a chiller tank. A low temperature coolant in the chiller tank is then refrigerated by the evaporator coil. The coolant is then pumped from the chiller tank through a spiral wall pipe in an area to be air conditioned, removing heat by conduction, convection, and evaporative cooling, and returned to the chiller tank to be cooled and recirculated. The coolant in the chiller tank is maintained at a desired temperature by the refrigeration system. The temperature in the conditioned area is controlled by the temperature and flow of the coolant in the spiral wall pipe. A heating system supplies hot water to the above air conditioning system while bypassing the refrigeration system. Humidification and cleaning are achieved by an overhead pipe which is perforated, and water or cleaning solution is pumped under low pressure and dispersed down onto the spiral wall pipe.

Abstract: In a thermostatic expansion valve having a thermo bulb, a valve opening degree is defined by the force difference between a first force at one side surface of a diaphragm and a second force at the other side surface thereof. The former force is the sum of the pressure of a refrigerant, sensed at the downstream side of a valve seat and applied on one side surface by an auxiliary pressure applying capillary tube, and the biasing force, applied on one side surface by a valve body spring. The latter force is the sum of the pressure of an actuator vapor, contained in a thermal bulb and applied on the other side surface of the diaphragm, and the pressure of the refrigerant, sensed at the upstream side of the valve seat in a refrigerant pathway of a valve housing and applied on the other side surface by way of a force transmitting member.
