Abstract: A refrigerant heat pump system is operable in both heating and cooling modes. A reheat circuit is integrated into the system schematic to provide improved control over temperature and humidity and to cover a wide spectrum of sensible and latent capacity demands. In the heating mode, the reheat coil is utilized to act as a portion of the enlarged indoor heat exchanger (a condenser in this case), in order to enhance system efficiency without the capacity loss. In some cases, where the designer can choose between the efficiency and capacity augmentation, selective operation of the reheat coil may offer an additional step of capacity modulation, in the heating mode. System reliability is improved through a reduction of start/stop cycles. Although various reheat coil arrangements in relation to the indoor and outdoor heat exchangers are offered and reheat concepts are considered, the benefits of the invention are independent from and transparent to such system design features.

Abstract: A system and method for measuring fluid flow rate in a system where fluid is pumped, such as a gas monitoring instrument where gas is pumped from a space such as a room or enclosure through a conduit to a sensor. The flow of gas through a pump is determined by measuring motor back-e.m.f. which is proportional to motor speed. In a system where motor speed is regulated by pulse width modulation of the motor drive voltage, the back-e.m.f. is sampled during intervals between the drive pulses applied to the motor, and in a further aspect the sampling is done at selected, spaced-apart or infrequent intervals such as once for every ten or once for every hundred motor drive pulses. Advantageously, in an instrument that uses a microprocessor and analog-to-digital converter to measure gas-concentration, the same microprocessor and converter can provide the PWM control of the pump, in response to the back-e.m.f. generated by the pump motor between the drive pulses.

With the selector valve in a third position between the first and second positions, pressure is bled from the machine to disable the smoke generating apparatus and thereby terminate the production of smoke.
