They’re super-efficient in mild weather, and could even cost less to install than a central air conditioner. Heat pumps might save money vs. propane, electric resistance heat, and heating oil. Almost any well-installed heat pump should cost less to run over the course of a heating season...
A heat pump is a machine or device that diverts heat from one location (the 'source') at a lower temperature to another location (the 'sink' or 'heat sink') at a higher temperature using mechanical work or a high-temperature heat source.A heat pump can be used to provide heating or ...
Heat pumps act as an air conditioner when it's hot and a heater when it’s cold. Find out how you can benefit from a heat pump's flexibility and efficiency.
Air source heat pumps vs. geothermal heat pumps: what to know Both ASHPs and GSHPs are efficient and clean technologies, but there are a few factors to consider when deciding between using one or the other: Technology Air Source Heat Pump ...

clustering analysis; air-to-air heat pump; heating patterns; heating operation time periods; heating duration1. Introduction 1.1. Background In recent years, severe air pollution occurred in China’s northern regions, which has affected people’s lives [1]. The pollution showed obvious seasonal ...
The heat pump integrated with the storage module uses R410a refrigerant and has a nominal power of 14 kW. The compressor is equipped with an air-cooled inverter drive (VACON INU series, model NXI0095) that allows DC-powered operation in the range of 465–800 VDC, varying also the driving...
Based on the energy environment requirements of the ULEBs, a new concept of the integrated heat pump environment control unit with outdoor air (IEU) has been proposed [103]. As shown in Fig. 18, this system consists of a fresh air unit and an ASHP unit, which has the ability to cont...
