STORAGE TYPE HEAT PUMP HOT WATER SUPPLYING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240133588 titled 'STORAGE TYPE HEAT PUMP HOT WATER SUPPLYING APPARATUS
Simplified Explanation
The patent application describes a storage type heat pump hot water supplying apparatus that controls the compressor frequency and pump rotational speed to maintain a target hot water discharge temperature during a heat accumulating operation.
- Control circuitry manages compressor frequency and pump rotational speed
- Compressor frequency is higher in the first operation of heat accumulating, lower in the second operation
- Pump rotational speed is adjusted to achieve target hot water discharge temperature
- Heat accumulating operation consists of two phases with different target temperatures
Potential Applications
This technology can be applied in residential and commercial buildings for efficient hot water supply systems.
Problems Solved
1. Inefficient hot water storage and supply systems 2. Inconsistent hot water temperatures
Benefits
1. Energy savings 2. Consistent hot water temperature 3. Improved overall system efficiency
Potential Commercial Applications
Optimizing hot water supply systems in hotels, hospitals, and apartment buildings.
Possible Prior Art
There may be prior art related to heat pump systems for hot water supply, but specific examples are not provided in the abstract.
Unanswered Questions
How does the control circuitry determine the optimal pump rotational speed for achieving the target hot water discharge temperature?
The abstract mentions that the control circuitry adjusts the pump rotational speed to reach the target temperature, but it does not detail the specific method or algorithm used for this adjustment.
What are the specific differences in operation between the first and second phases of the heat accumulating operation?
While the abstract mentions that the compressor frequency and target temperature vary between the two phases, it does not explain the reasons for these differences or how they contribute to the overall efficiency of the system.
Original Abstract Submitted
a storage type heat pump hot water supplying apparatus includes: control circuitry to control a compressor frequency and a pump rotational speed, the compressor frequency being an operating frequency of the compressor, the pump rotational speed being a rotational speed of a water pump. the control circuitry is configured to control, in a heat accumulating operation for accumulating hot water in the hot water storage tank, the pump rotational speed so that the actual hot water discharge temperature becomes equal to a target hot water discharge temperature. the heat accumulating operation includes a first operation and a second operation after the first operation. the compressor frequency in the first operation is higher than the compressor frequency in the second operation. the target hot water discharge temperature in the first operation is lower than the target hot water discharge temperature in the second operation.
