Heat pump system and heat pump device using a constant flow reverse stirling cycle

A constant flow reverse Stirling cycle heat pump system comprising:

• a constant flow isothermal compression means for compressing a working gas, said compression means including a drive means, an inlet, and an outlet, and further including a cooling means to remove heat of compression from said working gas;
• a constant flow isothermal expansion means for expanding said working gas, said expansion means including an inlet, an outlet, and a heat source means to provide isothermal expansion of said working gas while removing heat from said heat source means;
• and
• a constant volume regenerative heat exchange means for transferring heat from compressed working gas to expanded working gas, said constant volume regenerative heat exchange means comprising:
• an enclosure, said enclosure containing
• a high pressure portion with an inlet receiving compressed working gas from said compression means outlet and with an outlet discharging regeneratively cooled working gas to said expansion means inlet,
• a low pressure portion with an inlet receiving expanded working gas from said expansion means outlet and with an outlet discharging regeneratively heated working gas to said compression means inlet,
• a slotted rotor in a central portion of said enclosure, said rotor containing a plurality of radially extending slots, and
• a plurality of radially sliding vanes mounted in said slots and extending to seal against a wall of said enclosure, wherein a first portion of said wall having a constant first radial distance from said rotor cooperates with said vanes to form a first constant volume channel defining said high pressure portion and a second portion of said wall having a constant second radial distance from said rotor cooperates with said vanes to form a second constant volume channel defining said low pressure portion, said first radial distance being less than second radial distance;
• and
• heat transfer means in thermal contact with said high pressure portion and said low pressure portion for transferring heat from said compressed working gas to said expanded working gas.
