摘要： An improved single-stage snow thrower including a wheeled frame assembly for supporting the snow thrower upon a ground surface and a driven impeller capable of being placed in ground contact to forwardly propel the snow thrower across the ground surface. A handle assembly including a user interface is further provided to permit the operator to selectively control the normal force associated with the driven impeller, and thus selectively control the propulsive drive force of the snow thrower. A bail control assembly may be provided upon the handle to permit the operator to selectively control a downward movement of the impeller to selectively control the degree of impeller ground contact.

摘要： The present invention provides for noise reduction during operation of a portable blower by reducing the noise or acoustic energy escaping from the housing outlet and blower tube. The noise reduction is achieved by placing sound absorbing material in the blower tube. The sound absorbing material may include flared upstream and downstream ends to reduce turbulence. The sound absorbing material may be held within the blower tube by an insert frame such that substantial portions of the sound absorbing material are exposed to air passing through the blower tube. Also disclosed is a sound absorbing insert that can be placed within an existing blower tube to retrofit portable blowers with noise reduction technology.

摘要： A compensation circuit for sensor lag uses a sensor temperature signal modification circuit to provide a modified sensor temperature signal for subsequent use in controlling the sensed temperature. The compensation circuit digitally compares a current sensor temperature representative signal and a sensor temperature signal at a last or preceeding sample time to produce a difference signal which is converted to a sensor slope signal and is multiplied by a sensor time constant. The resulting signal is passed through a filter to eliminate transient effects and is summed with the original sensor temperature signal to provide a sensed temperature signal for control of the temperature whereby the sensed temperature is a better estimate of the actual environmental temperature controlled by a thermostat utilizing the sensed temperature signal.

摘要： A refrigeration system control method for minimizing off cycle losses in a heating mode of operation includes the steps of closing a valve in a refrigerant line between an indoor coil and an outdoor coil for a first predetermined period of time starting with a deenergization of a compressor and ending before a reenergization of the compressor to retain the refrigerant in the indoor coil and maintaining an energization of an indoor coil fan for a second predetermined time period after the deenergization of the compressor which second time ends before the first time period. An apparatus using this method includes an indoor condensor coil, an indoor coil fan, an outdoor evaporator coil, an outdoor coil fan, a refrigerant line connecting one end of the outdoor coil to one end of the indoor coil, a valve in the refrigerant line, a compressor means connecting the other end of the indoor coil to the other end of the outdoor coil and a timer for operating the valve, the indoor fan, the outdoor fan and the compressor in a predetermined sequence to produce a closed state of the valve for a first time period starting after a compressor operation and ending before a restoration of a compressor operation while maintaining an energization of the indoor fan for a second time period after a compressor operation and ending before the first time period to utilize the latent energy stored in the refrigerant and in the metal coil of the indoor coil.

摘要： A comfort control system and method which determines the operating temperature set point for the environment to be controlled, in part by indirectly measuring the mean radiant temperature of the environment. A temperature sensor and relative humidity sensor sense the environment to be controlled and provide electrical signals indicating the sensed values to a microprocessor. A building load monitor either monitors the duty cycle of the heating/cooling system for the environment or senses the difference between the environment temperature and the outside temperature to generate a value indicative of the heating or cooling load on the building. A calculation formula to be stored in the microprocessor factors the selected operating temperature, the building load, the relative humidity, and selected constance. The microprocessor determines the operating set point, compares the set point to the temperature of the environment, and generates a control signal for the heating/cooling system. A method of controlling the comfort of an environment comprises the steps of sensing the air temperature and relative humidity of the environment, monitoring the building load, accessing the selected temperature and selected constant values for use in an operating set point calculation formula, calculating the operating temperature set point, comparing the operating temperature set point with the sensed room temperature, and generating a control signal for the heating/cooling system based on the comparison.

摘要： A temperature control system for a multiplant environmental unit such as a heat pump with auxiliary heat is disclosed. The control system utilizes a thermostat having a microprocessor and memory that allows for energy savings through setback functions. The setback functions return the temperature control from a setback temperature to a normal comfort temperature along a ramped rate that is modified from day to day. The purpose of this variable ramp is to minimize the operation of the auxliary heat and maximize shell savings (by starting as late as possible). This is basically accomplished by locking the heat pump on in certain cases.

摘要： A control system for a refrigeration heat pump apparatus and an auxiliary heating apparatus has a two stage thermostat with the first stage normally controlling the heat pump apparatus and the second stage normally controlling the auxiliary heating apparatus. An outdoor temperature thermostat is used to transfer the control of the auxiliary heating apparatus to the first stage when the outdoor temperature drops below a predetermined value and the heat pump is deenergized as its efficiency drops at that low outdoor temperature. Each of the stages of the thermostat has an anticipation means such as a heater to artificially heat the temperature responsive element. In order to improve the control and reduce the large change in temperature when the auxiliary heat is switched over to the first stage, both of the anticipation heaters of the first and second stage are connected to be controlled by the first stage during the operation of auxiliary heat by the first stage.

摘要： An improved air inlet cover and impeller for a convertible electric blower/vacuum. The blower/vac includes an electric motor which drives an impeller. A plurality of blades located on the impeller define a frusto-conical surface of revolution. The air inlet cover includes an integral, frusto-conical pressure ring which is located offset but generally congruent to the surface of revolution defined by the impeller blades. The cover additionally includes an air grate that allows the passage of air but prevents the passage of other objects. The grate also includes a choke member for adjusting the effective area of the air inlet into the blower/vac to control the exit air volume and velocity of the blower. The cover also includes a bell-mouthed opening integral with the choke member to increase the efficiency of the blower/vac when in the blower mode.
