Abstract: The disclosed airconditioner has a refrigerant compressor connected to a refrigerant circuit through a four-way valve in each of the room cooling mode and a first room warming mode of operation. The refrigerant circuit has an indoor heat exchanger, an externally heated heat exchanger, a piping, a first electromagnetic valve and an outdoor heat exchanger connected in series. A second electromagnetic valve is connected in parallel to the outdoor heat exchanger between the piping and the four-way valve to form the refrigerant circuit along with the indoor heat exchanger, the externally heated heat exchanger and the piping for the second room warming mode of operation. During the room cooling mode and first room warming mode of operation, the first electromagnetic valve is opened and the piping and the externally heated heat exchanger hold an amount of liquid refrigerant equal to the volume of the outdoor heat exchanger, while in the second room warming mode of operation in which the second electromagnetic valve and an electromagnetic valve connected across the compressor are open the outdoor heat exchange is filled with liquid refrigerant.

Abstract: A method of operating an air conditioning system including a refrigeration circuit having a compressor and a thermostat for sensing heating and cooling needs together with an indoor fan is disclosed. The indoor fan operation is controlled based upon a microprocessor control remembering whether or not the unit was in continuous fan operation prior to the compressor operating to satisfy a heating or cooling need. Through the setting of a flag the microprocessor remembers the previous inputs such that operation of the fan may be controlled regardless of the condition of the compressor especially as concerns operation of the fan when the compressor is prevented from operating due to a safety, overload or timed off condition.

Abstract: The cooling performance of an air conditioning apparatus is controlled by a selective combination of three methods of regulation, in accordance with the required degree of cooling. A first stage of regulation controls the volume of air delivered by a fan 6, a second stage controls the amount of refrigerant flowing through a pressure reduction means 7, and a third stage controls the amount of refrigerant circulating in a compressor feedback circuit 9. Any one of or combination of these three controls may be employed in accordance with the prevailing temperature condition and the required cooling performance.

Abstract: A forced air heating and cooling system employs a water source heat pump as the primary heating source and as a back-up or supplementary source of cooling. Supplementary heating is supplied by an electrical heater such as resistance heater, while primary cooling is provided by a water coil heat exchanger. Separate thermostats control the heat pump on the one hand, and the resistance heater and water coil heat exchanger on the other hand; the two thermostats can be combined in a simple unit. The thermostats automatically control two valves which control system water flow. For cooling, a first valve opens to permit water flow in series through first the water coil and then the heat pump. For heating, only the second valve is opened to bypass the water coil and deliver water directly to the heat pump. The water is ground water derived from a well, spring or lake. The thermostats automatically switch on the heat pump, heater and/or heat exchanger to effect the necessary heating or cooling.

Abstract: An automotive air conditioning apparatus is provided which, in raising the temperature inside a vehicle cabin from a low level to a preset higher level in a maximum cooling mode or in lowering the cabin temperature from a high level to a preset lower level in a maximum heating mode, suitably controls in an initial stage of the procedure the revolution speed of a blower but does not drive an air mix door at all to keep it at an existing opening degree. When the revolution speed of the blower reaches a predetermined lowest speed, the air mix door begins to be driven to vary its opening degree progressively and suitably while, at the same time, a first reference temperature level for deactivating a compressor associated with a cooler is shifted to a second reference temperature level.

Abstract: Microprocessor controlled apparatus is provided for automatically diagnosing faults in a heat pump system. Temperature sensors located at strategic points in the system are read periodically in accordance with a preprogrammed diagnostic routine. Temperature measurements preferably representing comparison of two temperature readings that produce temperature differentials outside pre-established tolerance limits are stored with a fault identification representative of the corresponding fault measurement. A service technician can read the fault data from storage by activation of control means for that purpose whereby the nature of the causative fault or faults can readily be determined.

Abstract: A reverse air cycle type heat pump is provided that utilizes a refrigeration system having a unidirection refrigerant flow wherein the condenser and evaporator retain their functions, but the air directed across them is redirected for different operations. The refrigeration system is provided with a secondary defrost circuit including a first conduit between the upper portion of the evaporator and the compressor casing and a second conduit having a valve which permits refrigerant flow to by-pass the expansion device only when compresssor operation terminates and the system pressure differential is equalized. This defrost circuit causes the relatively warm refrigerant in gaseous phase in the compressor to displace the relatively cold refrigerant in liquid phase in the evaporator with the flow continuing until the defrost process is completed.
