An HVAC system for a vehicle having a battery pack, and a method of operation, is disclosed. The HVAC system may comprise a refrigerant loop having a first leg and a second leg, and a refrigerant compressor in the refrigerant loop. In the first leg, an evaporator provides cooling to a passenger cabin of the vehicle, an evaporator shut-off valve selectively blocks the flow of refrigerant through the evaporator, and an evaporator thermal expansion valve is upstream from the evaporator. In the second leg, a battery heat exchanger receives the refrigerant, a battery thermal expansion valve is located upstream from the battery heat exchanger, and a battery cooling shut-off valve selectively blocks the flow of refrigerant through the battery heat exchanger. The shut-off valves and compressor are controlled to control the cooling of the passenger cabin and the battery pack.

The invention discloses a control method and device for an air conditioner. The method comprises the steps of acquiring a current operation parameter of the air conditioner and a first operation powercorresponding to the current operation parameter; determining a target operation parameter obtained by correcting the current operation parameter and a second operation power corresponding to the target operation parameter; and controlling the air conditioner to operate according to the target operation parameter when it is detected that the second operation power is smaller than the first operation power. The control method and device for the air conditioner solve the technical problem that since a traditional control strategy is adopted in the prior art, it is difficult to control the air conditioner to operate under an optimal operation state.

The invention discloses an automatic variable loading device for a hydraulic spring. A central power unit with dual pumps is adopted and is connected with an independent valve station corresponding to each coal pulverizer; a pipeline is connected to the valve station to three hydraulic cylinders of the bottom of the coal pulverizer; and the hydraulic cylinder is connected with a spring rack of the coal pulverizer through a loading lever near the coal pulverizer. Each oil pump set of the central power unit comprises a high-pressure axle flow piston pump, a low-pressure gear pump and an electric motor. The electric motor of each pump set drives the high-pressure axle flow piston pump and the low-pressure gear pump to operate so as to pump hydraulic oil to an oil supply pipeline and transport the hydraulic oil to the valve station. The hydraulic oil with constant pressure from a main oil station is transported to the hydraulic cylinder through the valve station; and subsequently, the hydraulic oil reflows to a main oil tank of the main oil station. The device can solve the technical problems that the prior MPS coal pulverizer fails to automatically adjust the loading force in time according to the power output of the coal pulverizer in operation, thereby causing the weak capacity of load adaptability.
