Heat pattern (part 308).During on the contrary, air themperature is higher than switching temperature 306 around, heat storage
Heat pump 100 may operate in refrigerating mode (part 310).Switching temperature can be stored in system control
In device 131 processed, and can adjust.
After step 204, method 200 proceeds to step 206.In step 206, compressor control
Air compressor motor 109 is operated to unaltered state or change state according to operational mode by device 114.As
Upper described, when heat storage heat pump is in refrigerating mode, compressor controller 114 will compression electromechanics
Motivation 109 operates to unaltered state, or efficient state.Heat storage heat pump 100 is at heated mould
Time in formula, air compressor motor 109 is operated to change state by compressor controller 114, in this state
Its COP is reduced.This can include a few sub-steps, as shown in Figure 4.
Seeing Fig. 4, in sub-step 206a, compressor controller 114 can be from air compressor motor 109
Three mutually at least one be offset from set angle.Such as, compressor controller 114 can be by mutually
One be offset from 30 degree.In sub-step 206b, compressor controller 114 can change three mutually in extremely
Few one be defined frequency.As it has been described above, each runs to be defined frequency.Change in them
At least one can reduce COP.Should be understood that step 204 can include sub-step 206a and 206b
In any one, it can perform in any order.It is further understood that step 206 can include
More sub-steps, wherein air compressor motor 109 can otherwise change, such as built-in motor
Mechanical loss (or friction loss) within restrictive condition, air compressor motor 109, mechanical braking etc.,
To reduce COP.
