A cooling/heating system using a heat pump is provided to minimize heat loss in cooling and heating by using natural convection within the heat storage tank so as to stabilize the flow of fluid. A cooling/heating system, in which a compressor, a first heat exchanger, an expansion valve and...
PURPOSE:To provide a heating system, employing a heat pump, which sharply saves energy even when a heat source is located in a remote place and a heat source temperature is low by a method wherein a material the phase of which is changeable is contained in heat source fluid and heating ...
Check power supply. That can include aheat pump circuit breakerand or/a regular-looking wall switch close to the unit. That is another easy fix. I have responded to heat pump no heat or heat pump, not cooling calls, only to find the power was off inadvertently. Perhaps relatives were vi...
A hot water supply system has a first refrigerating circuit (R1) in parallel to a heating circuit (K) and a second refrigerating circuit (R2), and a brine circuit (B) in parallel to the second refrigerating circuit. The brine circuit circulates brine in a brine heat exchanger (9). The...
If your cooling or heat pump system isn't working, start here. POST a QUESTION or COMMENT about how to diagnose and repair air conditioning and heat pump systems. This page lists key articles explaining how to diagnose and fix an air conditioner & heat pump system that's not working; we...
Passive-cooling systems provide cooling by pumping cool water or antifreeze through the system without using the heat pump to assist the process. 选择语言:从 到 翻译结果1翻译结果2 翻译结果3翻译结果4翻译结果5 翻译结果1复制译文编辑译文朗读译文返回顶部 被动式冷却系统,通过该系统不使用热泵协助抽水过...
This can happen when the heat pump mode has not been switched from heating to cooling (or vice versa) to match the change in temperature. If you’ve checked the temperature settings but the temperature still isn’t as required, make sure that the thermostat isn’t being exposed to direct ...
Optimal design of ground source heat pump system integrated with phase change cooling storage tank in an office building Ground source heat pump system integrated with phase change cooling storage technology could save energy and shift peak load. This paper studied the optima... Y Lei,N Zhu,B ...
