Abstract

The invention discloses a thermostatic flow regulating device of a single-heating type heat-pump water heating unit and a control method of the thermostatic flow regulating device, relates to a control device for utilizing a fluid heater of a heat pump, in particular to a thermostatic flow regulating device for a dual-system single-heating type heat-pump water heating unit and a control method of the thermostatic flow regulating device. The thermostatic flow regulating device comprises a single chip microcomputer control unit, a temperature-sensing element, a switching signal element and a control signal output driving unit. The single chip microcomputer control unit is connected to a compressor, a water inlet electromagnetic valve, a thermostatic flow valve, a by-pass valve and a thermostatic water pump of the dual-system single-heating type heat-pump water heating unit through the control signal output driving unit. An outlet temperature set value is taken as a target value, opening of the thermostatic flow valve is controlled according to an outlet water temperature measured value, and water flow is regulated; when water tank temperature is low, the unit runs thermostatically; when inlet water temperature is over-high, the by-pass valve is turned on; when one of dual systems is faulted to stop running, outlet water set temperature is lowered so as to guarantee the other non-fault system to be capable of running efficiently, safely and stably.

Description

technical field [0001] The invention relates to a control device for a fluid heater using a heat pump, in particular to a constant temperature flow regulating device and a control method for a dual-system primary heating heat pump hot water unit. Background technique [0002] The current non-renewability of "fossil energy" such as coal, oil, and natural gas and the rapid reduction of global reserves have brought about a worldwide energy shortage. Coupled with the deteriorating ecological environment of the earth, it is necessary to protect the ecological environment and accelerate development and utilization. Renewable energy has become an urgent and arduous task for mankind. As an energy-saving and environment-friendly air source heat pump water heater, it has also been widely recognized. The bright market prospect of energy-saving products has also produced a revolutionary replacement trend for traditional water heating equipment. Air source heat pump hot water products m...
