Drying unit and laundry washing/drying machine equipped with the drying unit

In a laundry washing/drying machine involving drying by a heat pump cycle, in an initial stage of the drying operation the heat within an air circulation path is deficient and therefore it is impossible to effect quick heating of air on a drum inlet side up to a sufficiently high temperature. According to the present invention there is provided a drying unit capable of raising the drum inlet air temperature quickly up to a sufficiently high temperature in an initial stage of the drying operation and thereby shortening the drying time. The drying unit includes a heat pump cycle device for performing a cycle of radiating, with use of a radiator, the heat of a refrigerant compressed by a compressor, passing the refrigerant through a pressure reducing/expansion valve, evaporating the refrigerant in an evaporator and compressing the refrigerant again by the compressor, an air circulation path for allowing air to be circulated by a blower in such a manner that air heated by the radiator is introduced into a drying chamber to dry the laundry, exhaust air discharged from the drying chamber is passed through the evaporator, then is heated again by the radiator and the air thus dehumidified is circulated by the blower, and an external heat source applying device for applying the heat of an external heat source to the evaporator to quicken the rise in temperature of the air in an initial stage of the drying operation.

Cryogenic refrigeration unit suited for delivery vehicles

An apparatus to refrigerate the cargo space of delivery vehicles. It provides an environmentally friendly alternative to conventional mechanical a/c and refrigeration units. Cooling is provided by controlled evaporation of a liquefied gas such as CO.sub.2 or nitrogen. Defrost and heating requirements, if needed, are provided by hot engine coolant or by electric heaters powered from the vehicle electrical system. Airflow for the evaporator and for circulation in the temperature controlled space is provided by a blower which is mechanically or electrically driven from vehicle power. This invention can also be applied to multi-temperature control applications. The apparatus is compact and is particularly suited for small inner city delivery vehicles. FIG. 1: The sketch shows an inner city delivery truck for which this invention is most suitable. Refrigerated goods are placed in roller cages that are designed to maximize cargo hauled by use of roller cages that extend to within 2 inches of the ceiling. The evaporator section of this invention is mounted at or near the front wall of the truck and is separated from the cargo by a vertical bulkhead. The conditioned air is delivered at the bottom of the truck to avoid top freeze of perishable cargo that is in close proximity to the ceiling. FIG. 2: This shows the piping schematic and is similar to the invention described in U.S. Application Serial No. 60/238,929 (the '929 application) incorporated herein by reference. FIG. 2 shows the engine coolant coil located ahead of the CO.sub.2 coil in the direction of airflow. This prevents the coldest air from coming in contact with the engine coolant--in the cooling mode the air leaving the CO.sub.2 coil can be as low as F. for frozen load applications and this may cause the engine coolant to start freezing. Arrangements must be made to circulate air between the two coils in defrost mode. One means to accomplish this is to place a damper at the outlet of the evaporator section and run the fans. The damper would be closed during defrost. Another method is to place the engine coolant coil on the discharge side of the CO.sub.2 coil and use a cut-out switch if the engine coolant temperature drops below a predetermined value. In this arrangement there is no need for the damper arrangement as the heat will rise to melt any frost on the CO.sub.2 coil. If electric heat is used for defrost and heating freezing of the engine coolant is not a concern and the heaters can be fastened to the discharge side of the CO.sub.2 coil. An electric stand-by mode can be provided to power the system for cooling, heating and defrost when the vehicle is parked with the engine off. A plug-in electrical cable can provide the power needed for the controls, the fans and for heating and defrost. The figure shows the electric heaters attached on the discharge side of the CO.sub.2 coil. Operation: Detailed description is in the '929 application except for the following: The evaporator section is designed for vertical installation to maximize cargo space. Air is discharged at the bottom but may be a conventional top discharge if needed for specific applications. Conventional methods can be used to provide defrost and heating. If engine coolant is used for a heat source, it is preferable to thermally isolate the CO.sub.2 coil from the engine coolant coil to avoid freezing the coolant. The evaporator blower may be located on the inlet side of the coils rather than as shown in the figures. Unique Features: 1. Absence of a conventional condensing section on the exterior of the vehicle makes this an ideal refrigeration unit for small inner city delivery vehicles. Many of the truck cabs are now almost full height (same as the truck body) and there is limited space for the condensing section. 2. Cold plates can be used and still maximize cargo cube. However, this invention has 30-40% less weight than comparable "cold plate" systems. 3. Other features are described in the '929 application.]
