Abstract: The invention belongs to the technical field of vending machines and provides a vending machine refrigeration module, including a compressor, an evaporator, a condenser controller and a temperature sensor. The temperature sensor feeds back a detected temperature value to the controller. The detected temperature value is compared with a set temperature value to automatically adjust the motor speed of the compressor, the fan speed of the evaporator, and the fan speed of the condenser. The refrigeration module provided by the invention can automatically adjust the rotation speed of the compressor motor, the evaporator fan and the condenser fan according to the temperature detected by the temperature sensor, thereby avoiding full speed operation and reducing energy consumption and avoiding energy waste, improving energy efficiency.

Abstract: An embodiment provides an air conditioner, including: an outer housing that contains therein one or more of a condenser, a compressor, coils, a fan, an enclosure air intake, and an enclosure air return; one or more rainwater drains configured to transmit rainwater that enters the housing through the outer housing to ambient; and one or more condenser drains configured to transmit condensation from within the outer housing to an exterior location via one or more conduits.

Abstract: One example provides a cooling system, including: a first side configured to face an ambient environment; a second side configured to face an enclosure interior; a flange that surrounds the system and is configured for attachment to an opening of the enclosure; a thermostat; one or more fans; one or more compressors; and a controller configured to: utilize two or more set points and input from the thermostat to variably control the one or more fans and one or more compressors using variable direct current (VDC).

Abstract: An embodiment provides for cooling of a server rack enclosure. In one example, an evaporator includes: an evaporator housing having: a first surface having a first end that includes a warm air inlet that conducts warm air from inside a server rack enclosure and second end that includes a cool air outlet that returns cooled air to the server rack enclosure; evaporator coils positioned between the warm air inlet and the cool air outlet that cool the warm air from the inside of the server rack enclosure; and an airflow generating unit that provides airflow between the warm air inlet and the cool air outlet, the airflow transiting about the evaporator coils. The evaporator coils include tubing positioned in a connection port of the evaporator housing. The tubing is configured to attach to a remote condenser unit. Other embodiments are described and claimed.

Abstract: The invention is applicable to the technical field of heat sinks, and provides a heat dissipating device and a vending machine. The heat dissipating device comprises a fan, a fan motor and a heat dissipating cavity; the fan is connected with the fan motor, and the heat dissipating cavity comprises a first end surface close to the fan and away from the fan. a second end surface; the first end surface and the second end surface further comprise a plurality of sets of heat dissipating copper tubes parallel to the first end surface and disposed in the same direction, and the heat dissipating copper tubes in each set of heat dissipating copper tubes are parallel to each other, and the same group of heat dissipating The copper tube is also covered with a wide gap metal mesh; wherein the fan motor is a positive and negative motor; when the vending machine refrigeration system is started, the fan motor is reversed within a preset time to drive the fan to reverse, so that the heat dissipation cavity is obtained.
