Abstract
Official abstract text for this publication.
An auxiliary heater control device can be readily attached to a hot water heating system configured with a simple water circuit without a hot water storage tank, and is capable of preventing freezing of circulating water such that use of an auxiliary heater is minimized. When a sensed temperature tS sensed by a temperature sensor is in a range, a control device increases a rotational speed of a circulation pump. When the sensed temperature tS is in a range, the control device increases the rotational speed of the circulation pump and lowers an operating frequency of a compressor. When the sensed temperature tS is in a range, the control device increases the rotational speed of the circulation pump, lowers the operating frequency of the compressor, and activates an auxiliary heater.
First claim
Opening claim text (preview).
The invention claimed is: 1. An auxiliary heater control device for an auxiliary heater arranged in a fluid circulation circuit for circulating a fluid, the fluid circulation circuit including in a fluid circulation direction, a heat exchanger of a heat pump apparatus, the heat pump apparatus configured to perform a defrost operation and a normal heat pump operation wherein the heat pump apparatus includes a compressor, the auxiliary heater, a heated fluid utilization apparat…
