A self-contained water cooler module for use with a water dispenser includes a chassis. The chassis includes a back panel, a pair of spaced side panels extending forwardly from the back panel, a bottom panel extending forwardly from the back panel and attached to bottom edges of the pair of spaced side panels, and the back panel, side panels and bottom panel are constructed of a single, unitary sheet. A strut interconnects front edges of the pair of spaced side panels. A support bracket interconnects the back panel and the horizontal frame member. A refrigeration unit includes an evaporator, a condenser, a fan and motor assembly, and a compressor. The refrigeration unit is attached to the chassis. A water storage tank is configured to receive cooled water from the refrigeration unit. The chassis is configured to be attached to and detached from the water dispenser via a tool-free connection.

A refrigeration appliance comprises a fan mounting assembly mountable to a liner of a cabinet. The fan mounting assembly comprises a bracket, a first member of a first snap coupling on the bracket for receiving a corresponding second member of the first snap coupling on an evaporator coil cover, and a mounting flange having a first member of a snap lock extending from the bracket for mounting the fan mounting assembly to the liner of the cabinet. An evaporator coil cover for mounting to the fan mounting assembly comprises a second member of the first snap coupling allowing the evaporator coil cover to be coupled to the fan mounting assembly, and a first slot. An air tower assembly mountable to the fan mounting assembly through the first slot comprises a second member of a second snap coupling and a second member of a third snap coupling.

A duct system for a refrigerator appliance is provided. A fresh food supply duct provides fluid communication between an evaporator chamber and a fresh food chamber. A convertible chamber supply and return duct each provide fluid communication between the evaporator chamber and a convertible chamber. A dual damper is operably coupled to the convertible chamber supply and return duct for selectively and simultaneously opening or closing the convertible chamber supply duct and the convertible chamber return duct.

A refrigeration appliance with multiple storage compartments has a refrigerant circuit with a first expansion valve, a first heat exchanger, a second expansion valve, and a second heat exchanger connected in series between pressure and suction connections of a compressor. Each heat exchanger is associated with at least one storage compartment in order to control its temperature. A control unit controls the compressor rotational speed and positions of the expansion valves. The control unit has a continuously linear regulator for each storage compartment with a P-component for estimating a required temperature control output using a difference between actual and target temperatures. A model computing unit ascertains a target evaporation temperature for a first storage compartment controlled by the first heat exchanger, and for a second storage compartment controlled by the second heat exchanger. The heat exchangers are operated by selecting the compressor rotational speed and the valve positions of the expansion valves.

The present application provides an evaporator. The evaporator may include a housing, a coil assembly mounted within the housing, and a fan housing positioned within the housing. The fan housing may include a fan and a replaceable venturi ring sized to accommodate the fan.

Proposed is a refrigerator in which the internal air of a first storage compartment of two storage compartments whose temperatures are controlled by an evaporator is reintroduced into the evaporator by a circulating air path guide to be circulated, whereby even if an evaporator having small capacity is applied, freezing or refrigeration temperature may be freely embodied, and the circulation of cold air can be efficiently performed without interference.

A refrigeration module of a cold space chamber has a blower and an evaporator. A method of controlling the refrigeration module includes defrosting a coil of the evaporator to form a volume of warm air surrounding the coil. The method includes circulating a refrigerant through the evaporator after defrosting the coil, to cool the coil. The method includes operating the blower in a series of pulses to control introduction of the volume of warm air into the cold space chamber.

Provided are a control method for a refrigerating and freezing device, and the refrigerating and freezing device. The refrigerating and freezing device includes a cabinet provided with a groove communicating with a surrounding environment and sunken inwards, and at least one fan for promoting air of the surrounding environment to flow into the groove. The control method includes: judging whether a temperature in the groove is less than or equal to a dew point temperature; and if yes, controlling the fan to operate at a first preset rotation speed. The temperature in the groove is increased by controlling the fan to operate to introduce hot air of the surrounding environment into the groove when the temperature in the groove is less than or equal to the dew point temperature, which avoids condensation in the groove and improves safety and reliability of electrical parts in the groove.

An air-cooled refrigerator comprises a bottom liner, a fan bottom shell, an air duct cover plate, and fan blades. A cooling chamber and a storage space are defined in the bottom liner. The fan bottom shell is arranged at a rear portion of the cooling chamber. The air duct cover plate comprises a back plate portion and a fan upper cover. The back plate portion is disposed in front of a rear wall of the bottom liner. The fan upper cover obliquely extends downward from a lower end of the back plate portion into the cooling chamber, covers the fan bottom shell and is fastened thereto. The back plate portion and the fan upper cover are integrally formed. The fan blades are arranged in a fan cavity, and enable formation of a refrigeration airflow discharged from the cooling chamber to an air supply duct.
