    摘要： A refrigeration cycle has high-pressure and low-pressure refrigerant sides and causes at least a variable-capacity compressor and an outdoor heat exchanger, both of which are arranged outside the room to be air-conditioned, to communicate with an indoor heat exchanger arranged inside the room. The refrigeration cycle is operated in a heating operation mode. An inverter generates an output having a predetermined operating frequency to be supplied to the variable-capacity compressor. A fan commonly supplies an air flow to the outdoor heat exchanger and the inverter. A detector detects a signal corresponding to the pressure of the high-pressure refrigerant in the refrigeration cycle. A first control section provides a command for causing the inverter to gradually decrease the predetermined operating frequency when a detection signal from the detector exceeds a predetermined value. A second control section monitors a decrease in the predetermined operating frequency in the inverter due to the first control section, and provides a stop command to the fan when the predetermined operating frequency is decreased to a predetermined value or less.

    摘要： An air conditioning system for an enclosed space including a jointly driven compressor and expander of the positive displacement type each having an inlet port and an outlet port with a primary heat exchanger connected between the compressor outlet port and expander inlet port and a secondary heat exchanger connected between the expander outlet port and the compressor inlet port to complete a closed loop having a charge of air and with one of the heat exchangers being thermally coupled to the enclosed space. Ambient air is injected into the closed loop to raise the pressure in the secondary heat exchanger to substantially above the atmospheric level to increase the heat rate of the system. Alternatively air is bled from the loop to reduce the pressure in the secondary heat exchanger thereby to decrease the heat rate of the system. In one embodiment of the invention a blocking valve in the path of the air stream flowing through the secondary heat exchanger is momentarily closed to create a vacuum at the compressor inlet port and an injector valve at the compressor inlet port is coincidentally opened so that ambient air is injected by the process of aspiration. While the system may be manually controlled, it is one of the features of the invention that injection and bleeding are under the automatic and corrective control of a temperature pressure sensing device so that the heat rate of the system is varied automatically in accordance with the requirements of an enclosed space for automatic maintenance of a present condition. The system is usable in a refrigerating mode, making use of the absorption of heat in the secondary heat exchanger or in the heat pump mode utilizing the dissipation of heat in the primary heat exchanger, with automatic control of space temperature in both of the modes.

    摘要： An air conditioning system for an enclosed space which includes a compressor and expander having inlet and outlet ports with a primary heat exchanger connected between the compressor outlet port and the expander inlet port and a secondary heat exchanger connected between the expander outlet port and the compressor inlet port to complete a closed loop having a charge of air, one of the heat exchangers being thermally coupled to the enclosed space. A pump is provided for injecting air into the loop to increase the pressure therein thereby to increase the heat rate of the system. Preferably the pump is used for both injecting air into the loop and bleeding air from the loop under the control of a thermostat for maintenance of a set temperature; however, a simplified form of the invention employs constant bleed. In a more elaborate form of the invention pressure follow-up is incorporated in the control to avoid any tendency toward overshoot.

    摘要： A super heat calculator for air conditioning systems comprising a microprocessor, a control panel, a temperature sensor, and a pressure sensor. Vapor pressure models for all expected air conditioning refrigerants are stored in a data storage unit of the microprocessor. Positioning a rotary switch on the control panel directs the microprocessor to utilize the vapor pressure model associated with the refrigerant assigned to the switch position. The temperature sensor and pressure sensor are installed between the evaporator and compressor of the air conditioning system. The temperature and pressure signals are sent to a dual slope analog to digital converter located in the control panel. The temperature of the refrigerant is automatically displayed when the calculator is turned on. Pressing the SUPER-HEAT button on the control panel initiates calculation of the degree of super heat. The microprocessor reads the refrigerant temperature and pressure values and stores them in the storage unit. The data processor accesses the vapor pressure model that corresponds to the refrigerant selected by the rotary switch and calculates the vapor temperature which corresponds to the sensed refrigerant pressure by interpolation. The data processor then calculates the super heat value by subtracting the calculated vapor temperature from the value of the sensed refrigerant temperature.

    摘要： A self-cleaning heat exchanger (10) has a reversible fan (12) located between two tube banks (14, 16) with a pressure switch (24) connected thereto. The fan (12) rotates in one direction blowing across the first tube bank (14) and drawing air over the second tube bank (16). The pressure switch and fan are interconnected by two relays (28, 30). When the refrigerant pressure in the tube banks exceeds the threshold pressure, the relay (28) is closed and grounded and electric current flows through the relay (30). The change in direction of current flow will reverse the polarity of the windings in motor (13) and thus the rotation of the motor (13) and the fan (12) thereby reversing air flow to remove debris from one tube bank while withdrawing heat from the other without loss of cooling efficiency.

    摘要： A microprocessor-based air conditioning/refrigeration control system adapted for use with a variable speed compressor measures acceleration of the compressor and the temperature or pressure of the refrigerant exiting therefrom, determines the rate of change of the temperature or pressure of the refrigerant, and decreases acceleration of the compressor if the rate of change of the temperature or pressure of the working fluid indicates surging of the compressor. Superheat of the refrigerant is maintained at a first predefined level while the compressor is operating at constant speed and is increased to a second, higher predefined level while the compressor is accelerating. The system is able to diagnose deterioration of the compressor by measuring and comparing power input to the compressor and rate of change of temperature or pressure of the refrigerant at the compressor between initial and subsequent periods, and differentiate between deterioration of a drive component or a pressurizing component of the compressor.
