Title: Method and device for controlling heat pump

Abstract

A method for controlling a heat pump is provided. A working mode of the heat pump is determined. Based on a determination that the working mode of the heat pump is a heating mode, an ambient temperature of the heat pump is determined. Based on a determination that the ambient temperature of the heat pump is higher than a first predetermined temperature, a first compressor of the heat pump is operated. Based on a determination that the ambient temperature of the heat pump is lower than the first predetermined temperature, both the first compressor and a second compressor of the heat pump are enabled to operate, in response to a two-stage thermostat. The first compressor and the second compressor are coupled in parallel. The method allows the heat pump to be suitable for a cold climate.

Cold Climate Heat Pump using Tandem Vapor-Injection Compressors

Conference Shen, Bo; Abdelaziz, Omar; Baxter, Van; ...

Conventional air-source heat pumps (ASHPs) experience rather poor performance in cold climate areas. The heating capacity and efficiency of con-ventional ASHPs decrease significantly as the outdoor temperature decreases. The major R&D challenges are to limit this ASHP heating capacity and efficiency degradation at low and extremely low ambient temperatures. Vapor injection (VI) compressors are able to provide better efficiency and larger capacity at low ambient temperatures. A prototype air-source cold climate heat pump (CCHP), using tandem vapor injection (VI) compressors and inter-stage flash tank, was developed. The CCHP has two identical VI compressors in parallel, which works with a two-stagemore »« less
Cost-Optimized Cold Climate Heat Pump Development and Field Test

Technical Report Munk, Jeffrey; Shen, Bo; Gehl, Anthony

Cold climate heat pumps (CCHPs) expand the heat pump market to climates where heating demand is dominant. They can achieve more than 70% energy savings compared with electric resistance heating and operate at lower cost than using tank-stored propane to fuel a furnace. A high-efficiency heat pump with a heating seasonal performance factor (HSPF)—as defined by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI 2008)—greater than 10.0 would be more efficient than gas heating in terms of source energy. However, developing a cost-effective CCHP involves some challenges. A typical single-speed, air-source heat pump (ASHP) with an HSPF of 7.7 Btu/Wh doesmore »« less

Cold Climate Heat Pumps Using Tandem Compressors

Conference Shen, Bo; Abdelaziz, Omar; Rice, C; ...

In cold climate zones, e.g. ASHRAE climate regions IV and V, conventional electric air-source heat pumps (ASHP) do not work well, due to high compressor discharge temperatures, large pressure ratios and inadequate heating capacities at low ambient temperatures. Consequently, significant use of auxiliary strip heating is required to meet the building heating load. We introduce innovative ASHP technologies as part of continuing efforts to eliminate auxiliary strip heat use and maximize heating COP with acceptable cost-effectiveness and reliability. These innovative ASHP were developed using tandem compressors, which are capable of augmenting heating capacity at low temperatures and maintain superior part-loadmore »« less

Solar assisted heat pump heating system

Patent Pendergrass, J

A solar assisted heat pump fluid heating system capable of reliable operation at higher than normal ambient temperatures is disclosed. The system includes a collection of solar panels and primary fluid storage tanks having integral coiled heat exchangers interconnected and charged with heat transfer fluid to produce heat. Temperature sensors positioned at the panels and storage tanks transmit temperature signals to solar control circuit. At predetermined temperatures, the solar control circuit energizes a first circulation pump transferring heated fluid from the panels, effecting heat transfer with a low temperature working fluid stored in the tanks. A second circulation pump transfersmore »« less
Testing of refrigerant mixtures in residential heat pumps. Final report

Technical Report Judge, J; Radermacher, R

To contribute to finding the proper substitute for R-22, a test facility was designed and built to measure the steady state and cyclic performance of two air-to-air heat pumps of 2 & 3 refrigeration-ton (RT) capacity. The performance of heat pumps is evaluated based on ASHRAE Standard 116-1983 {open_quotes}Method of Testing for Seasonal Efficiency of Unitary Air-conditioners and Heat Pumps{close_quotes} (47). This standard includes six steady-state tests; three cooling tests (A, B, and C) and three heating tests (High Temperature (47S), Frost Accumulation (35F), and Low Temperature (17L)). The standard also includes two cyclic tests; a cyclic cooling test (D)more »« less
