摘要： A guide frame for a four-way reversing valve includes a frame body. Both ends of the frame body include a connecting portion, respectively. The connecting portion includes a first bending member and a second bending member, and the directions of bending of the first bending member and of the second bending member are opposite. The connecting portion includes a reinforcing member. The reinforcing member includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is connected to the inner side of the first bending member by welding and the second reinforcing plate is connected to the inner side of the second bending member by welding. The connection strength of the connecting portion is increased, such that the guide frame is less likely to deform or break.

摘要： The present teachings provide a modular air source heat pump system (ASHP system) with an internal assembly, an external assembly, a refrigerant module, sensors, and a control system. The refrigerant module is removably connected to the external assembly. The sensors are located within the internal assembly and configured to monitor internal conditions, internal system conditions, or both. The sensors are located within the external assembly and configured to monitor external conditions, external system conditions, or both. The control system in communication with the sensors located within the internal assembly and the external assembly. The control system is configured to: change a heat transfer fluid charge in the internal assembly, the external assembly, or both by adding or subtracting heat transfer fluid from the refrigerant module in response to changes in the external conditions, the external system conditions, the internal conditions, the internal system conditions, or a combination thereof.

摘要： The present invention aims to provide an application of an ammonium ion-containing halogen compound in solid-state refrigeration and a novel efficient solid-state refrigeration method driven by a pressure. The ammonium ion-containing halogen compound is characterized in that phase change can be induced with only a small pressure, resulting in a huge barocaloric effect, and the unit pressure thereof drives the phase-change temperature displacement as high as 0.81 Kmin−1. Ammonium iodide produces 89.07 J kg−1K−1 isothermal entropy change under a pressure of 20 MPa; and the use of this material for a refrigeration cycle is far superior to other material systems having a barocaloric effect.
