Abstract:
The present invention concerns a method for controlling the operation of an automotive HVAC system. The HVAC system includes at least a refrigerant compressor and a refrigerant evaporator. The method includes the steps of calculating an ambient air enthalpy value; comparing the calculated ambient air enthalpy value to at least one predetermined enthalpy value; and selectively changing the operation of the refrigerant compressor based on the comparison.
Abstract:
A vehicular air conditioner includes a reversible heat pump having an air distribution fan positioned upstream of an indoor heat exchanger, a coolant heat exchanger positioned downstream of the indoor heat exchanger, and a damper arranged adjacent to a coolant heat exchanger. An engine cooling water system is connected to the coolant heat exchanger. A subassembly is used for positioning the damper in the fully opened condition such that the coolant heat exchanger is made an air intake flow path in addition to an air flow path of an air bypass space during a cooling operation. The engine cooling water system includes a coolant bypass valve connected between a primary side flow path and a secondary side flow path for engine cooling water to bypass the coolant heat exchanger. When the damper fully opens a full quantity of the engine cooling water flows to the secondary side flow path.
Abstract:
An air conditioner for a vehicle having an engine that serves as a drive source for a compressor arranged in a rear part of the vehicle. The air conditioner includes the compressor, and further includes an air intake unit having an inside air intake, an outside air intake, an inside air/outside air changeover damper, and a blower disposed on a downstream side of the inside air/outside air changeover damper. The air conditioner includes an air conditioning unit into which air is introduced from the air intake unit, provided along an introduced air distribution path with a cooling apparatus heat exchanger fluidly connected to the compressor and configured to exchange heat between the introduced air and air outside the cabin interior, where the cooling apparatus heat exchanger is located in the rear part of the vehicle. The air conditioning unit also include an engine heat exchanger configured to exchange heat between the introduced air and an engine of the vehicle. The air conditioner further includes a duct configured to distribute air from the air conditioning unit to a front part of the vehicle, where the duct is provided with air outlets configured to discharge the air into the cabin interior.
Abstract:
An object of the invention is to provide a vehicular air conditioner using a heat pump that can improve heating ability by effective utilization of engine waste heat during a heating operation. The apparatus of the invention is a vehicular air conditioner using a heat pump with a compressor unit 20 equipped with a compressor 31, a throttling resistance 34 and a four way valve 33, connected by a refrigerant path 30 to an indoor heat exchanger 25 for effecting heat exchange between a refrigerant and vehicle cabin air, and an outdoor heat exchanger 21 installed in an engine compartment for effecting heat exchange between a refrigerant and outside air, and equipped with fan 22 for drawing in outside air, and which executes a cooling operation and a heating operation by switching a direction of flow of the refrigerant. During the heating operation, if the temperature of the engine compartment goes above a predetermined value, the fan 22 for drawing in outside air is reversed so that high temperature air is discharged from the engine compartment to the outside.
Abstract:
A solid-phase polymerization method of high-molecular-weight aliphatic polyester conducts the solid-phase polymerization of aliphatic polyester prepolymer under a gas stream containing sulfonic acid catalyst. The method features preparing metal free aliphatic polyester with high molecular weight, good color and luster and perfect thermal stability efficiently. The non-metal-ion aliphatic polyester is not only applicable to common use, but is also suitable as high value-added medical material and packing material which contacts with food directly than other metal-containing polyester.

A system for testing an artificial memory includes a monitor (10), a driver (20), and an executing means (30). The monitor includes a command line interface (101) for inputting commands and parameters. The driver includes a command line editor (201), which is adapted to be activated before the command line interface is used; a command translator (202) for invoking corresponding subprograms according to the input commands and parameters; an error flag (203) for indicating whether any error occurred during the testing; and an error counter (204) for counting the number of times any error occurred during the testing. The executing means is for testing the memory with reading/writing of sequence bit strings, and returning test results to the monitor via the driver. A related method for testing an artificial memory is also provided.
Abstract:
A flow management device is provided for managing refrigerant flow in a reversible HVAC system. Refrigerant lines from the system heat exchangers connect to bi-directional ports on the flow management device which converts the high pressure refrigerant flowing in one bi-directional port into pressure reduced refrigerant that flows out of the other bi-directional port. The flow management device has multiple bi-directional ports and a flow path for refrigerant extending between the ports. Flow sensitive valves are positioned within the flow path to prevent high pressure refrigerant from flowing between the ports. A pressure reducing device is arranged so that high pressure refrigerant flowing into one of the ports flows through one of the flow sensitive valves and then into the pressure reducing device. Pressure reduced refrigerant emitted from the pressure reducing device flows through a multi-function valve and out the other port. The invention can further integrate the receiver/drier function into the flow management device providing a centralized device for filtering refrigerant flow and ensuring a continuous supply of liquid refrigerant to the pressure reducing device. Also, outlets can be added to the receiver portion of the flow management center to provide a source of high pressure liquid refrigerant for secondary heat exchangers.
